7.11. mysqlhotcopyA Database Backup Program
mysqlhotcopy is a Perl script that was originally written and contributed by Tim Bunce. It uses LOCK TABLES, FLUSH TABLES, and cp or scp to make a database backup quickly. It is the fastest way to make a backup of the database or single tables, but it can be run only on the same machine where the database directories are located. mysqlhotcopy works only for backing up MyISAM and ARCHIVE tables. It runs on Unix and NetWare.
shell> mysqlhotcopy db_name [/path/to/new_directory] shell> mysqlhotcopy db_name_1 ... db_name_n /path/to/new_directory
Back up tables in the given database that match a regular expression:
shell> mysqlhotcopy db_name./regex/
The regular expression for the table name can be negated by prefixing it with a tilde ('~')
shell> mysqlhotcopy db_name./~regex/
mysqlhotcopy supports the following options:
mysqlhotcopy reads the [client] and [mysqlhotcopy] option groups from option files.
To execute mysqlhotcopy, you must have access to the files for the tables that you are backing up, the SELECT privilege for those tables, and the RELOAD privilege (to be able to execute FLUSH TABLES).
Use perldoc for additional mysqlhotcopy documentation, including information about the structure of the tables needed for the --checkpoint and --record_log_pos options:
shell> perldoc mysqlhotcopy
