9 mysqlhotcopy arguments

12 mysqlhotcopy is a Perl script that was originally written and
13 contributed by Tim Bunce. It uses FLUSH TABLES, LOCK TABLES, and cp or
14 scp to make a database backup. It is a fast way to make a backup of the
15 database or single tables, but it can be run only on the same machine
16 where the database directories are located. mysqlhotcopy works only
17 for backing up MyISAM and ARCHIVE tables. It runs on Unix and NetWare.
18 To use mysqlhotcopy, you must have read access to the files for the
20 tables that you are backing up, the SELECT privilege for those tables,
21 the RELOAD privilege (to be able to execute FLUSH TABLES), and the LOCK
22 TABLES privilege (to be able to lock the tables).
23 shell> mysqlhotcopy db_name [/path/to/new_directory]
25 shell> mysqlhotcopy db_name_1 ... db_name_n /path/to/new_directory
27 Back up tables in the given database that match a regular expression:
29 shell> mysqlhotcopy db_name./regex/
31 The regular expression for the table name can be negated by prefixing
33 it with a tilde (“~”):
34 shell> mysqlhotcopy db_name./~regex/
36 mysqlhotcopy supports the following options, which can be specified on
38 the command line or in the [mysqlhotcopy] and [client] option file
39 groups.
40 · --help, -?
42 Display a help message and exit.
44 · --addtodest
46 Do not rename target directory (if it exists); merely add files to
48 it.
49 · --allowold
51 Do not abort if a target exists; rename it by adding an _old
53 suffix.
54 · --checkpoint=db_name.tbl_name
56 Insert checkpoint entries into the specified database db_name and
58 table tbl_name.
59 · --chroot=path
61 Base directory of the chroot jail in which mysqld operates. The
63 path value should match that of the --chroot option given to
64 mysqld.
65 · --debug
67 Enable debug output.
69 · --dryrun, -n
71 Report actions without performing them.
73 · --flushlog
75 Flush logs after all tables are locked.
77 · --host=host_name, -h host_name
79 The host name of the local host to use for making a TCP/IP
81 connection to the local server. By default, the connection is made
82 to localhost using a Unix socket file.
83 · --keepold
85 Do not delete previous (renamed) target when done.
87 · --method=command
89 The method for copying files (cp or scp). The default is cp.
91 · --noindices
93 Do not include full index files for MyISAM tables in the backup.
95 This makes the backup smaller and faster. The indexes for reloaded
96 tables can be reconstructed later with myisamchk -rq.
97 · --old-server
99 Connect to old MySQL-server (before v5.5) which doesn't have FLUSH
101 TABLES WITH READ LOCK fully implemented..
102 · --password=password, -ppassword
104 The password to use when connecting to the server. The password
106 value is not optional for this option, unlike for other MariaDB
107 programs.
108 Specifying a password on the command line should be considered
110 insecure. You can use an option file to avoid giving the password
111 on the command line.
112 · --port=port_num, -P port_num
114 The TCP/IP port number to use when connecting to the local server.
116 · --quiet, -q
118 Be silent except for errors.
120 · --record_log_pos=db_name.tbl_name
122 Record master and slave status in the specified database db_name
124 and table tbl_name.
125 · --regexp=expr
127 Copy all databases with names that match the given regular
129 expression.
130 · --resetmaster
132 Reset the binary log after locking all the tables.
134 · --resetslave
136 Reset the master.info file after locking all the tables.
138 · --socket=path, -S path
140 The Unix socket file to use for connections to localhost.
142 · --suffix=str
144 The suffix to use for names of copied databases.
146 · --tmpdir=path
148 The temporary directory. The default is /tmp.
150 · --user=user_name, -u user_name
152 The MariaDB user name to use when connecting to the server.
154 Use perldoc for additional mysqlhotcopy documentation, including
156 information about the structure of the tables needed for the
157 --checkpoint and --record_log_pos options:
158 shell> perldoc mysqlhotcopy
