To use mysqlhotcopy, you must have read access to the files for the tables that you are backing up, the SELECT privilege for those tables, the RELOAD privilege (to be able to execute FLUSH TABLES), and the LOCK TABLES privilege (to be able to lock the tables).
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, which can be specified on the command line or in the [mysqlhotcopy] and [client] option file groups.
Display a help message and exit.
Do not rename target directory (if it exists); merely add files to it.
Do not abort if a target exists; rename it by adding an _old suffix.
Insert checkpoint entries into the specified database db_name and table tbl_name.
Base directory of the chroot jail in which mysqld operates. The path value should match that of the --chroot option given to mysqld.
Enable debug output.
Report actions without performing them.
Flush logs after all tables are locked.
The host name of the local host to use for making a TCP/IP connection to the local server. By default, the connection is made to localhost using a Unix socket file.
Do not delete previous (renamed) target when done.
The method for copying files (cp or scp). The default is cp.
Do not include full index files for MyISAM tables in the backup. This makes the backup smaller and faster. The indexes for reloaded tables can be reconstructed later with myisamchk -rq.
Connect to old MySQL-server (before v5.5) which doesn't have FLUSH TABLES WITH READ LOCK fully implemented..
The password to use when connecting to the server. The password value is not optional for this option, unlike for other MariaDB programs.
Specifying a password on the command line should be considered insecure. You can use an option file to avoid giving the password on the command line.
The TCP/IP port number to use when connecting to the local server.
Be silent except for errors.
Record master and slave status in the specified database db_name and table tbl_name.
Copy all databases with names that match the given regular expression.
Reset the binary log after locking all the tables.
Reset the master.info file after locking all the tables.
The Unix socket file to use for connections to localhost.
The suffix to use for names of copied databases.
The temporary directory. The default is /tmp.
The MariaDB user name to use when connecting to the server.
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
