TABLE OF CONTENTS

9   Introduction to Holland
10       Holland  is  an  Open  Source  backup framework originally developed by
11       Rackspace and written in Python. It's goal is to help facilitate  back‐
12       ing  up  databases with greater configurability, consistency, and ease.
13       Holland currently focuses on MySQL, however future development will in‐
14       clude  other  database platforms and even non-database related applica‐
15       tions. Because of it's plugin structure, Holland can be used to  backup
16       anything you want by whatever means you want.
17
18       Python2 support has been removed as of holland 1.2.0
19
20   Dependencies
21       The core Holland framework has the following dependencies (available on
22       any remotely modern Linux distribution):
23
24       • Python >= 3.6
25
26       • pkg_resources
27
28       • python-setuptools
29
30       • ConfigParser
31
32       MySQL based plugins additional require the MySQLdb python connector:
33
34       • pyMySQL
35
36       Note that other plugins may have additional dependency requirements.
37
38   Holland Command-Line Reference
39       Here are the commands available from the 'holland' command-line tool:
40
41   help (h)
42       Usage: holland <command> --help(-h)
43
44       Provides basic information about the provided command. If no command is
45       provided, it displays global help instead.
46
47   backup (bk)
48       Usage: holland backup [backup-set1, backup-set2, ..., backup-setN]
49
50       Runs  the backup operation. If no backup-sets are specified, all active
51       backup-sets  (those  defined  in  the  'backupsets'  variable  in  hol‐
52       land.conf) are backed up.
53
54       One  or  more backup-sets can be specified directly, in which case only
55       those backup-sets are backed up.
56
57       Additional Command Line Arguments:
58
59       --dry-run (-n): Can be used here to simulate, but not actually  run,  a
60       backup. This should be used when troubleshooting a particular error be‐
61       fore trying to run a real backup.
62
63       --no-lock (-f): Normally, only one instance of Holland can run  at  any
64       given  time  using lock-files. Using this flag causes the lock-files to
65       be ignored. This has some very clear use-cases but otherwise be mindful
66       of using this setting as it can cause backups to fail in some cases.
67
68       --abort-immediately: abort on the first backup-set that fails (assuming
69       multiple backupsets were specified)
70
71       Examples:
72
73       # holland bk  --dry-run  weekly:  Attempts  a  dry-run  of  the  weekly
74       backup-set.
75
76       #  holland  bk  --no-lock --abort-immediately: Attempts a backup of all
77       the default backup-sets ignoring locks and aborting immediately if  one
78       of the backup-sets fails.
79
80   list-backups (lb)
81       Usage: holland list-backups
82
83       Provides extended information about available backups.
84
85   list-plugins (lp)
86       Usage: holland list-plugins
87
88       Lists all the available (installed) plugins available to Holland.
89
90   mk-config (mc)
91       Usage: holland mk-config <provider>
92
93       Generates  a  template  backup-set  for  a particular provider (such as
94       mysqldump).  By default, the output is sent to standard out but can  be
95       copied  to a file, either by using the --file, --edit, or -name options
96       (see below).
97
98       Additional Command Line Arguments:
99
100       --edit: Load the file into the system text-editor for further modifica‐
101       tions.
102
103       --file=FILE (-f): Write the output directly to provided file.
104
105       --name=NAME:  Creates  a  backup-set usable in Holland, which basically
106       means that a file is created of the provided name under the  backup-set
107       directory.
108
109       --provider: Indicates that the default provider configuration should be
110       outputted instead. This is really only used when  creating  a  provider
111       config specifically - it should not be used for backup-sets.
112
113       Examples:
114
115       # holland mk-config mysql-lvm > mysql-lvm.conf: Output the default con‐
116       figuration  for  MySQL-LVM  backups  and  write  the  contents  out  to
117       mysql-lvm.conf in the current working directory.
118
119       # holland mc mysqldump --name=Bob --edit: Create a backup-set using the
120       mysqldump provider named Bob  and  allow  interactive  editing  of  the
121       backup-set before saving the file.
122
123   purge (pg)
124       Usage: holland purge <backup-set>/<backup-id>
125
126       Purges old backups by specifying the backup-set name and set-id.
127
128       For  example:  #  holland purge mybackups/20090502_155438: Purge one of
129       the backups taken on May 2nd, 2009 from the mybackups backup-set.
130
131   Usage and Implementation Overview
132       Because Holland is very pluggable, it may first seem  a  bit  confusing
133       when it comes to configuring Holland to do something useful. Out of the
134       box, Holland is designed to backup MySQL databases using the  mysqldump
135       provider.   This  is the simplest setup, and may be sufficient for most
136       people. However, others may wish to have more fine-grained control over
137       their backups and/or use another method other than mysqldump.
138
139       For  instance,  one  can configure a backup set to backup certain data‐
140       bases using mysqldump, others using the mysql-lvm plugins etc. All this
141       is done by a mix of providers and backup-sets.
142
143   Backup-Sets
144       Each  backup-set  implements  exactly one provider and will inherit the
145       default values of that provider. These values can be overridden to  ad‐
146       just  the behavior of the backup set. This includes defining what data‐
147       bases or tables to include (or exclude) in the backup, the type of com‐
148       pression used (if any), what locking method to use, among other things.
149
150   Providers
151       Providers essentially provide a backup service for use in a backup set.
152
153       • mysqldump
154            Uses the mysqldump utility to backup databases.
155
156       • MySQL + LVM
157            Backup  MySQL  databases using LVM snapshots which allows for near
158            lockless or fully lockless (when transactional engines  are  used)
159            backups.
160
161       • mysqldump + LVM
162            This plugin creates an LVM snapshot, starts a mysql instance using
163            the snapshot as it's datadir, and then use the  mysqldump  utility
164            to backup the databases.
165
166       • XtraBackup
167            New in version 1.0.8.
168
169
170            Backup MySQL databases using Percona's XtraBackup tool.  This pro‐
171            vides a near lockless backup when using the InnoDB storage engine.
172
173       • pgdump
174            Backup PostgreSQL databases using the pgdump utility.
175
176       • pg_basebackup
177            New in version 1.2.8.
178
179
180            Backup PostgreSQL databases using the pg_basebackup utility.
181
182       • mariabackup
183            New in version 1.1.0.
184
185
186            Backup MySQL databases using MariaDB's mariabackup tool.
187
188       • mongodump
189            New in version 1.1.0.
190
191
192            This plugin performs logical backups of a  MongoDB  by  using  the
193            mongodump utility.
194
195       • Example
196            This is used solely as a template for designing providers. It oth‐
197            erwise does nothing.
198
199       As Holland is a framework, it can actually backup most anything as long
200       as  there  is a provider for it. This includes things that have nothing
201       to do with databases. The idea is to present an easy to use  and  clear
202       method of backing up and restoring backups no matter the source.
203
204   Holland Config Files
205       By  default,  Holland's configuration files reside in /etc/holland. The
206       main configuration file is holland.conf, however there are a number  of
207       other   configuration   files  for  configuring  default  settings  for
208       providers and for configuring backup sets.
209
210       Each configuration file has one ore more sections,  defined  by  square
211       brackets  Underneath each section, one or more configuration option can
212       be specified. These options are in a standard "option = value"  format.
213       Comments are prefixed by the # sign.
214
215       Note  that  many settings have default values and, as a result, can ei‐
216       ther be commented out or omitted entirely.
217
218   holland.conf - main config
219       The main configuration file (usually /etc/holland/holland.conf) defines
220       both  global  settings as well as the active backup sets. It is divided
221       into two sections [holland] and [logging].
222
223   [holland]
224       plugin-dirs
225              Defines where the plugins can be found. This can be a comma-sep‐
226              arated list but usually does not need to be modified.
227
228       backup_directory
229              Top-level directory where backups are held.
230
231       backupsets
232              A  comma-separated  list  of  all the backup sets Holland should
233              backup.   Each  backup  set  is  defined  in  /etc/holland/back‐
234              upsets/<name>.conf by default.
235
236       umask  Sets the umask of the resulting backup files.
237
238       path   Defines a path for holland and its spawned processes
239
240   [logging]
241       filename
242              The log file itself.
243
244       level  Sets  the  verbosity of Holland's logging process. Available op‐
245              tions are debug, info, warning, error, and critical
246
247       format Define the format of the log message. This options should be  in
248              the format defined by the 'logging' python library.
249
250              New in version 1.1.0.
251
252
253   Provider Configs
254       These  files  control  the global settings / defaults for the providers
255       used by the backup-sets. Many of these global settings can be  overrid‐
256       den if defined in a backup-set. Note that each provider's configuration
257       file should begin with [provider-name].
258
259   mysqldump Provider Configuration [mysqldump]
260       Backs up a MySQL database using the mysqldump tool.
261
262   [mysqldump]
263       mysql-binpath = /path/to/mysql/bin
264          Defines the location of the MySQL binary utilities. If not provided,
265          Holland will use whatever is in the path.
266
267       lock-method  = flush-lock | lock-tables | single-transaction | auto-de‐
268       tect | none
269          Defines which lock method to use. By default,  auto-detect  will  be
270          used.
271
272          • flush-lock
273                flush-lock  will place a global lock on all tables involved in
274                the backup regardless of  whether  or  not  they  are  in  the
275                backup-set.  If  file-per-database is enabled, then flush-lock
276                will lock all tables for every database being  backed  up.  In
277                other  words,  this  option may not make much sense when using
278                file-per-database.
279
280          • lock-tables
281                lock-tables will lock all tables involved in  the  backup.  If
282                file-per-database  is enabled, then lock-tables will only lock
283                all the tables associated with that database.
284
285          • single-transaction
286                Forces  the  use   of   --single-transaction   which   enabled
287                semi-transparent backups of transactional tables. Forcing this
288                can cause inconsistencies with non-transactional tables,  how‐
289                ever.   While  non-transactional  tables will still lock, they
290                will only lock when they are actually  being  backed  up.  Use
291                this  setting  with  extreme caution when backing non-transac‐
292                tional tables.
293
294          • auto-detect
295                Let Holland decide which option to use by checking to see if a
296                database  or backup-set only contains transactional tables. If
297                so, --single-transaction will be used.  Otherwise,  --lock-ta‐
298                bles will be used.
299
300          • none
301                Does  absolutely no explicit locking when backing up the data‐
302                bases or backup-set. This should only be used when backing  up
303                a slave and only after the slave has been turned off (ie, this
304                can be used with the stop-slave option).
305
306       exclude-invalid-views =  yes | no (default: no)
307          Whether to automate exclusion of invalid views that would  otherwise
308          cause  mysqldump to fail.  This adds additional overhead so this op‐
309          tion is not enabled by default.
310
311          When enabled, thos option will scan the INFORMATION_SCHEMA.VIEWS ta‐
312          ble and execute SHOW FIELDS against each view.  If a view is detects
313          as invalid, an ignore-table option will be added to exclude the  ta‐
314          ble.   Additionally, the plugin will attempt to save the view defin‐
315          ion to 'invalid_views.sql' in the backupset's backup directory.
316
317          New in version 1.0.8.
318
319
320       dump-routines = yes | no (default: yes)
321          Whether or not to backup routines in the backup set  directly.  Rou‐
322          tines  are  stored  in the 'mysql' database, but it can sometimes be
323          convenient to include them in a backup-set directly.
324
325          Changed in version 1.0.8: This option now enabled by default.
326
327
328       dump-events = yes | no
329          Whether or not to dump events explicitly. Like routines, events  are
330          stored  in  the  'mysql'  database. Nonetheless, it can sometimes be
331          convenient to include them in the backup-set directly.
332
333          Note: This feature requires MySQL 5.1 or later. The mysqldump plugin
334          will automatically disable events if the version of mysqldump is too
335          old.
336
337          Changed in version 1.0.8: This option is now enabled by default
338
339
340       stop-slave = yes | no
341          Stops the SQL_THREAD during the backup. This means that writes  from
342          the  master  will  continue to spool but will not be replayed.  This
343          helps avoid lock wait timeouts among  things  while  still  allowing
344          data to be spooled from the master.
345
346          Note  that  previous versions of Holland prior to 1.0.6 simply ran a
347          STOP SLAVE instead, which suspends both replication threads.
348
349       bin-log-position = yes | no
350          Record the binary log name and position at the time of  the  backup.
351          The  information  provied  by  this  option is collected just before
352          locking the database.
353
354          Note that if both 'stop-slave' and 'bin-log-position'  are  enabled,
355          Holland  will  grab  the  master binary log name and position at the
356          time of the backup which can be useful in using the backup to create
357          slaves  or for point in time recovery using the master's binary log.
358          This information is found within the 'backup.conf' file  located  in
359          the     backup-set     destination     directory    (/var/spool/hol‐
360          land/<backup-set>/<backup> by default). For example:
361
362              [mysql:replication]
363              slave_master_log_pos = 4512
364              slave_master_log_file = 260792-mmm-agent1-bin-log.000001
365
366       flush-logs = yes | no
367          Whether or not to run FLUSH LOGS in  MySQL  with  the  backup.  When
368          FLUSH LOGS is actually executed depends on which if database filter‐
369          ing is being used and whether or not file-per-database  is  enabled.
370          Generally  speaking,  it  does not make sense to use flush-logs with
371          file-per-database since the binary logs will not be consistent  with
372          the backup.
373
374       file-per-database = yes | no
375          Whether  or  not  to  split up each database into its own file. Note
376          that it can be more consistent an efficient to backup all  databases
377          into one file, however this means that restore a single database can
378          be difficult if multiple databases are defined in the backup set.
379
380       arg-per-database = JSON object
381          If file-per-database is enable  this  argument  is  ued  to  specify
382          mysqldump  arguments  per  database. It takes a JSON object with the
383          database names as keys.  Example:  {"employee1":  "--no-data"}  Adds
384          the  '--no-data'  argument  to the mysqldump command when backing up
385          the 'employee1' database
386
387          New in version 1.0.9.
388
389
390       additional-options = <mysqldump argument>[, <mysqldump argument>]
391          Can optionally specify additional options directly to  mysqldump  if
392          there  is no native Holland option available.  This option accepts a
393          comma delimited list of arguments to pass on the commandline.
394
395       extra-defaults = yes | no (default: no)
396          This option controls whether mysqldump will only read options as set
397          by  holland  or  if  additional options from global config files are
398          read.  By default, the plugin only uses optons as set in  the  back‐
399          upset  config  and includes authentication credentials only from the
400          [client] section in ~/.my.cnf.
401
402       estimate-method = plugin | const:<size> (default: plugin)
403          This option will skip some of the heavyweight queries  necessary  to
404          calculate the size of tables to be backed up.  If a constant size is
405          specified, then only table names are evaluated  and  only  if  table
406          filtering is being used. Additionally, engines will be looked up via
407          SHOW CREATE TABLE if lock-method = auto-detect,  in  order  for  the
408          plugin  to determine if tables are using a transactional storage en‐
409          gine.  With 'plugin', the default behavior of reading both size  in‐
410          formation and table names from the information schema is used, which
411          may be slow particularly for a large number of tables.

414   Database and Table filtering
415       databases = <glob>
416
417       exclude-databases = <glob>
418
419       tables = <glob>
420
421       exclude-tables = <glob>
422
423       The above options accepts GLOBs in comma-separated lists. Multiple fil‐
424       tering  options  can be specified. When filtering on tables, be sure to
425       include both the database and table name.
426
427       Be careful with quotes. Normally these are not needed, but  when quotes
428       are  necessary,  be sure to only quote each filtering statement, as op‐
429       posed to putting quotes around all statements.
430
431       Below are a few examples of how these can be applied:
432
433       Default (backup everything):
434
435          databases = *
436          tables = *
437
438       Using database inclusion and exclusions:
439
440          databases = drupal*, smf_forum,
441          exclude-databases = drupal5
442
443       Including Tables:
444
445          tables = phpBB.sucks, drupal6.node*, smf_forum.*
446
447       Excluding Tables:
448
449          exclude-tables = mydb.uselesstable1, x_cart.*, *.sessions
450
451   [compression]
452       Specify various compression settings, such as compression utility, com‐
453       pression level, etc.
454
455       method  =  gzip| gzip-rsyncable | pigz | bzip2 | pbzip2 | lzop | lzma |
456       gpg | zstd
457          Define which compression method to use. Note that some  methods  may
458          not  be available by default on every system and may need to be com‐
459          piled or installed.
460
461          For gpg compression, a key should already exist(gpg  --gen-key)  and
462          default-recipient must be configured in ~/.gnupg/gpg.conf.
463
464       inline = yes | no
465          Whether  or  not  to  pipe the output of the backup command into the
466          compression utility. Enabling this is recommended since  it  usually
467          only marginally impacts performance, particularly when using a lower
468          compression level.
469
470       level = 0-9
471          Specify the compression ratio. The lower the number, the  lower  the
472          compression  ratio,  but the faster the backup will take. Generally,
473          setting the lever to 1 or 2 results in favorable compression of tex‐
474          tual  data and is noticeably faster than the higher levels.  Setting
475          the level to 0 effectively disables compression.
476
477       bin-path = <full path to utility>
478          This only needs to be defined if the compression utility is  not  in
479          the usual places or not in the system path.
480
481       options = <string>
482          Add commandline options to the configuration compression command.
483
484          options = "-Q4"
485
486       split = yes | no
487          Defautls  to  no.  If set the backup will be piped through the split
488          command.  This may be useful for user's  with  large  databases,  as
489          some  backup  systems perform better with many smaller files instead
490          of 1 large one. This defaults to 1GB file size, so this option isn't
491          helpful if your dumps are smaller than that.
492
493          For python2.6, this option will be disabled if the subprocess32 mod‐
494          ule isn't avaiable.

508
509       The password for the MySQL user

512
513       The socket file to connect to MySQL with.

516
517       This would be used for connecting to MySQL remotely.

520
521       Used if MySQL is running on a port other than 3306.
522
523   MySQL LVM Provider Configuration [mysql-lvm]
524       Creates  an LVM snapshot of a running MySQL instance and performs a bi‐
525       nary-based backup with minimal locking. MySQL must be running on an LVM
526       volume with reserved space for snapshots. It is highly recommended that
527       this volume be separate from the one storing the resulting backups.
528
529   [mysql-lvm]
530       snapshot-size = <size-in-MB>
531          The size of the snapshot itself. By default it is 20% of the size of
532          the  MySQL LVM mount or the remaining free-space in the Volume Group
533          (if there is less than 20% available) up to 15GB.  If  snapshot-size
534          is  defined,  the  number  represents  the  size  of the snapshot in
535          megabytes.
536
537       snapshot-name = <name>
538          The name of the snapshot, the default being the name  of  the  MySQL
539          LVM volume + "_snapshot" (ie Storage-MySQL_snapshot)
540
541       snapshot-mountpoint = <path>
542          Where  to mount the snapshot. By default a randomly generated direc‐
543          tory under /tmp is used.
544
545       innodb-recovery = yes | no (default: no)
546          Whether or not to run an  InnoDB  recovery  operation.  This  avoids
547          needing  to  do  so  during  a  restore, though will make the backup
548          process itself take longer.
549
550       force-innodb-backup = yes | no (default: no)
551          Whether to attempt a backup even if the mysql-lvm plugin  thinks  it
552          cannot  obtain a good backup.  This can occur when innodb data files
553          are outside of the mysql datadir or exist on entirely separate logi‐
554          cal volumes.
555
556       lock-tables = yes | no (default: yes)
557          Whether  or not to run a FLUSH TABLES WITH READ LOCK to grab various
558          bits of information (such as the binary log name and position). Dis‐
559          abling  this  requires that binary logging is disabled and InnoDB is
560          being used exclusively. Otherwise, it is possible  that  the  backup
561          could contain crashed tables.
562
563       extra-flush-tables = yes | no (default: yes)
564          Whether  or  not to run a FLUSH TABLES before running the full FLUSH
565          TABLES WITH READ LOCK. Should make the FLUSH TABLES WITH  READ  LOCK
566          operation a bit faster.
567
568       archive-method      = tar | dir (default: tar)
569          Create a tar file of the datadir, or just copy it.
570
571   [tar]
572       exclude = pattern[, pattern...]
573
574       Patterns  to exclude from archive.   These should be relative paths and
575       are almost always relative to the mysql data directory.   For  instance
576       to  exclude binary logs in the data directory from the backup you might
577       specify: exclude = ./bin-log.*, mysql.sock
578
579       pre-args = <string>
580
581       Additional arguments to append to the tar commandline before the backup
582       path is specified.  This should be the full string as you might specify
583       on the commandline. Shell globbing is not supported.
584
585       For instance you might add the /etc/my.cnf  to  the  tar  archive  via:
586       pre-args = -C /etc ./my.cnf
587
588       post-args = <string>
589
590       Additional  arguments to append to the tar commandline after the backup
591       path is specified.  This should be a string exactly as you might  spec‐
592       ify on the commandline.  Shell globbing is not evaluated.

820          path  this will be found in holland's environment PATH as configured
821          in /etc/holland/holland.conf.
822
823       Changed in version 1.1.12: For xtrabackup version 8.0 or greater,  this
824       option is ignored
825
826
827       ibbackup = <name>
828          The  path to the ibbackup command to use.  By default, no --ibbackup
829          option is pass to the  innobackupex  script.   Usually  innobackupex
830          will detect this by itself and this should not need to be set.
831
832       stream = tar|xbstream|yes|no (default: tar)
833          Whether to generate a streaming backup.
834
835       Changed  in  version 1.0.8: 'tar' and 'xbstream' are now valid options.
836       The old stream = yes is now equivalent to stream = tar and stream =  no
837       disables  streaming entirely and will result in a normal directory copy
838       with xtrabackup
839
840
841       Changed  in   version   1.1.12:   For   xtrabackup   version   8.0   or
842       greater,'xstream' will be used unless this value is set to 'no'
843
844
845       apply-logs = yes | no (default: yes)
846          Whether  to  run innobackupex --apply-logs at the end of the backup.
847          This is only supported when  performing  a  non-streaming,  non-com‐
848          pressed  backup.   In  this  case, even if apply-logs = yes (the de‐
849          fault), the prepare stage will be  skipped.   Even  with  an  uncom‐
850          pressed,  non-streaming backup you may want to disable apply-logs if
851          you wish to use incremental backups.
852
853          New in version 1.0.8.
854
855
856       slave-info = yes | no (default: yes)
857          Whether to enable the --slave-info innobackupex option
858
859       safe-slave-backup = yes | no (default: yes)
860          Whether to enable the --safe-slave-backup innobackupex option.
861
862       no-lock = yes | no (default: no)
863          Whether to enable the --no-lock innobackupex option
864
865       tmpdir = <path> (default: ${backup_directory})
866          The path for the innobackupex --tmpdir option. By default this  will
867          use the current holland backup directory to workaround the following
868          bug: https://bugs.launchpad.net/percona-xtrabackup/+bug/1007446
869
870          New in version 1.0.8.
871
872
873       additional-options = <option>[, <option>...]
874          A list of additional options to pass to  innobackupex.   This  is  a
875          comma separated list of options.
876
877       pre-command = <command-string>
878          A  command to run prior to running this xtrabackup run.  This can be
879          used, for instance, to generate a mysqldump  schema  dump  prior  to
880          running  xtrabackup.   instances  of ${backup_directory} and ${back‐
881          updir} will be replaced with the current  holland  backup  directory
882          where the xtrabackup data will be stored.
883
884       strict = yes | no (default: yes)
885          If  strict  is  set to no, add --strict=OFF option to the xtrabackup
886          command. The strict option in xtrabackup prevents errors and warning
887          for invalid command line options.
888              New in version 1.2.10.

890
891   [compression]
892       Specify various compression settings, such as compression utility, com‐
893       pression level, etc.
894
895       method = gzip| gzip-rsyncable | pigz | bzip2 | pbzip2 | lzop |  lzma  |
896       gpg | zstd
897          Define  which  compression method to use. Note that some methods may
898          not be available by default on every system and may need to be  com‐
899          piled or installed.
900
901          For  gpg  compression, a key should already exist(gpg --gen-key) and
902          default-recipient must be configured in ~/.gnupg/gpg.conf.
903
904       inline = yes | no
905          Whether or not to pipe the output of the  backup  command  into  the
906          compression  utility.  Enabling this is recommended since it usually
907          only marginally impacts performance, particularly when using a lower
908          compression level.
909
910       level = 0-9
911          Specify  the  compression ratio. The lower the number, the lower the
912          compression ratio, but the faster the backup will  take.  Generally,
913          setting the lever to 1 or 2 results in favorable compression of tex‐
914          tual data and is noticeably faster than the higher levels.   Setting
915          the level to 0 effectively disables compression.
916
917       bin-path = <full path to utility>
918          This  only  needs to be defined if the compression utility is not in
919          the usual places or not in the system path.
920
921       options = <string>
922          Add commandline options to the configuration compression command.
923
924          options = "-Q4"
925
926       split = yes | no
927          Defautls to no. If set the backup will be piped  through  the  split
928          command.   This  may  be  useful for user's with large databases, as
929          some backup systems perform better with many smaller  files  instead
930          of 1 large one. This defaults to 1GB file size, so this option isn't
931          helpful if your dumps are smaller than that.
932
933          For python2.6, this option will be disabled if the subprocess32 mod‐
934          ule isn't avaiable.
935
936          New in version 1.1.13.

968          Defines the --format option for pg_dump.  This  defaults  to  --for‐
969          mat=custom.  The custom format is required for pg_restore to do par‐
970          tial restore as well as enabling parallel restores. If set  to  cus‐
971          tom, the --compress option will be passed to pgdump
972
973       additional-options = <command-string>
974          Pass additional options to the pg_dump command
975
976       Only the 'level' option will be used if 'format=custom'

1214          fault), the prepare stage will be  skipped.   Even  with  an  uncom‐
1215          pressed,  non-streaming backup you may want to disable apply-logs if
1216          you wish to use incremental backups.
1217
1218       slave-info = yes | no (default: yes)
1219          Whether to enable the --slave-info innobackupex option
1220
1221       safe-slave-backup = yes | no (default: yes)
1222          Whether to enable the --safe-slave-backup innobackupex option.
1223
1224       no-lock = yes | no (default: no)
1225          Whether to enable the --no-lock innobackupex option
1226
1227       tmpdir = <path> (default: ${backup_directory})
1228          The path for the innobackupex --tmpdir option.
1229
1230       additional-options = <option>[, <option>...]
1231          A list of additional options to pass to  innobackupex.   This  is  a
1232          comma separated list of options.
1233
1234       pre-command = <command-string>
1235          A command to run prior to running this mariabackup run.  This can be
1236          used, for instance, to generate a mysqldump  schema  dump  prior  to
1237          running  mariabackup.   instances of ${backup_directory} and ${back‐
1238          updir} will be replaced with the current  holland  backup  directory
1239          where the mariabackup data will be stored.
1240
1241   [compression]
1242       Specify various compression settings, such as compression utility, com‐
1243       pression level, etc.
1244
1245       method = gzip| gzip-rsyncable | pigz | bzip2 | pbzip2 | lzop |  lzma  |
1246       gpg | zstd
1247          Define  which  compression method to use. Note that some methods may
1248          not be available by default on every system and may need to be  com‐
1249          piled or installed.
1250
1251          For  gpg  compression, a key should already exist(gpg --gen-key) and
1252          default-recipient must be configured in ~/.gnupg/gpg.conf.
1253
1254       inline = yes | no
1255          Whether or not to pipe the output of the  backup  command  into  the
1256          compression  utility.  Enabling this is recommended since it usually
1257          only marginally impacts performance, particularly when using a lower
1258          compression level.
1259
1260       level = 0-9
1261          Specify  the  compression ratio. The lower the number, the lower the
1262          compression ratio, but the faster the backup will  take.  Generally,
1263          setting the lever to 1 or 2 results in favorable compression of tex‐
1264          tual data and is noticeably faster than the higher levels.   Setting
1265          the level to 0 effectively disables compression.
1266
1267       bin-path = <full path to utility>
1268          This  only  needs to be defined if the compression utility is not in
1269          the usual places or not in the system path.
1270
1271       options = <string>
1272          Add commandline options to the configuration compression command.
1273
1274          options = "-Q4"
1275
1276       split = yes | no
1277          Defautls to no. If set the backup will be piped  through  the  split
1278          command.   This  may  be  useful for user's with large databases, as
1279          some backup systems perform better with many smaller  files  instead
1280          of 1 large one. This defaults to 1GB file size, so this option isn't
1281          helpful if your dumps are smaller than that.
1282
1283          For python2.6, this option will be disabled if the subprocess32 mod‐
1284          ule isn't avaiable.
1285
1286          New in version 1.1.13.
1287
1288
1289   MySQL connection info [mysql:client]
1290       These  are  optional  and, if left undefined, Holland will try to login
1291       using the standard .my.cnf conventions.
1292
1293       user = <user>
1294
1295       The user to connect to MySQL as.
1296
1297       password = <password>
1298
1299       The password for the MySQL user
1300
1301       socket = <socket>
1302
1303       The socket file to connect to MySQL with.
1304
1305       host = <host>
1306
1307       This would be used for connecting to MySQL remotely.
1308
1309       port = <port>
1310
1311       Used if MySQL is running on a port other than 3306.
1312
1313   Backup-Set Configs
1314       Backup-Set configuration files largely inherit  the  configuration  op‐
1315       tions  of  the  specified provider. To define a provider for the backup
1316       set, you must put the following at the top of the backup set configura‐
1317       tion file:
1318
1319          [holland:backup]
1320          plugin = <plugin>
1321          backups-to-keep = #
1322          estimated-size-factor = #
1323          historic-size = <yes|no>
1324          historic-size-factor = #
1325          historic-estimated-size-factor = #
1326
1327   Configuration Options
1328       plugin = <plugin>
1329          This  is  the  name  of  the  provider  that  will  be  used for the
1330          backup-set.  This is required in order for the backup-set  to  func‐
1331          tion.
1332
1333       backups-to-keep = #
1334          Specifies  the number of backups to keep for a backup-set.  Defaults
1335          to retaining 1 backup.
1336
1337       estimated-size-factor = #
1338          Specifies the scale factor when Holland decides if there  is  enough
1339          free  space to perform a backup.  The default is 1.0 and this number
1340          is multiplied against what each individual plugin reports its  esti‐
1341          mated  backup  size  when Holland is verifying sufficient free space
1342          for the backupset.
1343
1344          As of Holland 1.1.1, the 'historic' backup size  will  be  used.  If
1345          Holland  is  unable  to determine that size, it will default back to
1346          this.
1347
1348       auto-purge-failures = yes | no
1349          Specifies whether to keep a failed backup or to automatically remove
1350          the backup directory.  By default this is on with the intention that
1351          whatever process is calling holland will retry when a backup  fails.
1352          This  behavior  can  be disabled by setting auto-purge-failures = no
1353          when partial backups might  be  useful  or  when  troubleshooting  a
1354          backup failure.
1355
1356       purge-policy = manual | before-backup | after-backup
1357          Specifies  when to run the purge routine on a backupset.  By default
1358          this is run after a new successful backup completes.   Up  to  back‐
1359          ups-to-keep backups will be retained including the most recent.
1360
1361          purge-policy  = before-backup will run the purge routine just before
1362          a new backup starts.  This will retain up to backups-to-keep backups
1363          before  the new backup is even started allowing purging all previous
1364          backups if backups-to-keep is set to 0.  This behavior is useful  if
1365          some other process is retaining backups off-server and disk space is
1366          at a premium.
1367
1368          purge-policy = manual will never run  the  purge  routine  automati‐
1369          cally.   Either  holland purge must be run externally or an explicit
1370          removal of desired backup directories can  be  done  at  some  later
1371          time.
1372
1373       before-backup-command = string
1374          Run  a  shell command before a backup starts.  This allows a command
1375          to perform some action before the backup starts such as  setting  up
1376          an  iptables  rule  (taking a mysql slave out of a load balancer) or
1377          aborting the backup based on some external condition.
1378
1379          The backup will fail if this command exits with a non-zero status.
1380
1381          New in version 1.0.7.
1382
1383
1384       after-backup-command = string
1385          Run a shell command after a backup completes.  This allows a command
1386          to  perform some action when a backup completes successfully such as
1387          sending out a success notification.
1388
1389          The backup will fail if this command exits with a non-zero status.
1390
1391          New in version 1.0.7.
1392
1393
1394       failed-backup-command = string
1395          Run a shell command if a backup starts.  This allows some command to
1396          perform  some action when a backup fails such as sending out a fail‐
1397          ure notification.
1398
1399          The backup will fail if this command exits with a non-zero status.
1400
1401          New in version 1.0.7.
1402
1403
1404       historic-size = yes | no
1405          Defaults to yes. Check for the 'backup.conf' file  in  the  'newest'
1406          spooled  folder  for  the running "backupset".  If the configuration
1407          file exists and contains 'estimated-size' and 'on-disk-size',  these
1408          values will be used to decide if holland has enough free space for a
1409          backupset. This means Holland will  use  values  from  the  previous
1410          backup to estimate the size of the next backup.
1411
1412          New in version 1.1.1.
1413
1414
1415       historic-size-factor = #
1416          Defaults to '1.5'. If the estimated size of the database has changed
1417          by more than this multiple, the 'estimated-size-factor'  value  will
1418          be used to determine if there is sufficient free space for the back‐
1419          upset.
1420
1421          New in version 1.1.1.
1422
1423
1424       historic-estimated-size-factor = #
1425          Defaults to '1.1'. Specifies the scale factor when  Holland  decides
1426          if  there  is  enough  free  space to perform a backup. Holland will
1427          throw an error if the system has  less  free  space  than  the  last
1428          backup size multiplied by this value
1429
1430          New in version 1.1.1.
1431
1432
1433       create-symlinks = yes | no
1434          Defaults  to  yes. Enable the creation of "newest" and "oldest" sym‐
1435          links in the backupset directory.  Disabling  the  symlink  creation
1436          process and be helpful on filesystems that don't support symlinks.
1437
1438          New in version 1.2.7.
1439
1440
1441          $ ls -l /var/spool/holland/default/
1442          total 0
1443          drwxrwx---. 3 root root 58 Aug 18 16:18 20210818_161856
1444          lrwxrwxrwx. 1 root root 42 Aug 18 16:18 newest -> /var/spool/holland/default/20210818_161856
1445          lrwxrwxrwx. 1 root root 42 Aug 18 16:18 oldest -> /var/spool/holland/default/20210818_161856
1446
1447       For all hook commands, Holland will perform simple text substitution on
1448       the three parameters:
1449
1450          • hook - name of the hook being called (one  of:  before-backup-com‐
1451            mand, after-backup-command, failed-backup-command)
1452
1453          • backupdir   -   path   to   the  current  backup  directory  (e.g.
1454            /var/spool/holland/mysqldump/YYYYmmdd_HHMMSS)
1455
1456          • backupset - name of the backupset being run (e.g. 'mysql-lvm')
1457
1458       For example:
1459
1460          [holland:backup]
1461          plugin = mysqldump
1462          before-backup-command = /usr/local/bin/my-custom-script --hook ${hook} --backupset ${backupset} --backupdir ${backupdir}
1463          after-backup-command = echo ${backupset} completed successfully.  Files are in ${backupdir}
1464
1465          [mysqldump]
1466          ...
1467
1468       Backup-Set files are defined in the "backupsets" directory which is, by
1469       default, /etc/holland/backupsets. The name of the backup-set is defined
1470       by its configuration filename and can really  be  most  anything.  That
1471       means  backup-sets  can  be  organized  in  any arbitrary way, although
1472       backup set files must end in .conf. The file extension is not  part  of
1473       the name of the backup-set.
1474
1475       As  noted  above,  in  order  for a backup-set to be active, it must be
1476       listed in the backupsets variable.
1477
1478       Backups are placed under the directory defined in the  backup_directory
1479       section of the main configuration file. Each backup resides under a di‐
1480       rectory corresponding to the backup-set name followed by a date-encoded
1481       directory.
