13 mysqlhotcopy is a Perl script that was originally written and
14 contributed by Tim Bunce. It uses FLUSH TABLES, LOCK TABLES, and cp or
15 scp to make a database backup. It is a fast way to make a backup of the
16 database or single tables, but it can be run only on the same machine
17 where the database directories are located. mysqlhotcopy works only
18 for backing up MyISAM and ARCHIVE tables. It runs on Unix and NetWare.
19 To use mysqlhotcopy, you must have read access to the files for the
21 tables that you are backing up, the SELECT privilege for those tables,
22 the RELOAD privilege (to be able to execute FLUSH TABLES), and the LOCK
23 TABLES privilege (to be able to lock the tables).
24 shell> mysqlhotcopy db_name [/path/to/new_directory]
26 shell> mysqlhotcopy db_name_1 ... db_name_n /path/to/new_directory
28 Back up tables in the given database that match a regular expression:
30 shell> mysqlhotcopy db_name./regex/
32 The regular expression for the table name can be negated by prefixing
34 it with a tilde (“~”):
35 shell> mysqlhotcopy db_name./~regex/
37 mysqlhotcopy supports the following options, which can be specified on
39 the command line or in the [mysqlhotcopy] and [client] option file
40 groups.
41 • --help, -?
43 Display a help message and exit.
45 • --addtodest
47 Do not rename target directory (if it exists); merely add files to
49 it.
50 • --allowold
52 Do not abort if a target exists; rename it by adding an _old
54 suffix.
55 • --checkpoint=db_name.tbl_name
57 Insert checkpoint entries into the specified database db_name and
59 table tbl_name.
60 • --chroot=path
62 Base directory of the chroot jail in which mysqld operates. The
64 path value should match that of the --chroot option given to
65 mysqld.
66 • --debug
68 Enable debug output.
70 • --dryrun, -n
72 Report actions without performing them.
74 • --flushlog
76 Flush logs after all tables are locked.
78 • --host=host_name, -h host_name
80 The host name of the local host to use for making a TCP/IP
82 connection to the local server. By default, the connection is made
83 to localhost using a Unix socket file.
84 • --keepold
86 Do not delete previous (renamed) target when done.
88 • --method=command
90 The method for copying files (cp or scp). The default is cp.
92 • --noindices
94 Do not include full index files for MyISAM tables in the backup.
96 This makes the backup smaller and faster. The indexes for reloaded
97 tables can be reconstructed later with myisamchk -rq.
98 • --old-server
100 Connect to old MySQL-server (before v5.5) which doesn't have FLUSH
102 TABLES WITH READ LOCK fully implemented..
103 • --password=password, -ppassword
105 The password to use when connecting to the server. The password
107 value is not optional for this option, unlike for other MariaDB
108 programs.
109 Specifying a password on the command line should be considered
111 insecure. You can use an option file to avoid giving the password
112 on the command line.
113 • --port=port_num, -P port_num
115 The TCP/IP port number to use when connecting to the local server.
117 • --quiet, -q
119 Be silent except for errors.
121 • --record_log_pos=db_name.tbl_name
123 Record master and slave status in the specified database db_name
125 and table tbl_name.
126 • --regexp=expr
128 Copy all databases with names that match the given regular
130 expression.
131 • --resetmaster
133 Reset the binary log after locking all the tables.
135 • --resetslave
137 Reset the master.info file after locking all the tables.
139 • --socket=path, -S path
141 The Unix socket file to use for connections to localhost.
143 • --suffix=str
145 The suffix to use for names of copied databases.
147 • --tmpdir=path
149 The temporary directory. The default is /tmp.
151 • --user=user_name, -u user_name
153 The MariaDB user name to use when connecting to the server.
155 Use perldoc for additional mysqlhotcopy documentation, including
157 information about the structure of the tables needed for the
158 --checkpoint and --record_log_pos options:
159 shell> perldoc mysqlhotcopy
