NAME
       mysqlhotcopy - a database backup program

SYNOPSIS
       mysqlhotcopy arguments

DESCRIPTION
       mysqlhotcopy is a Perl script that was originally written and contributed by Tim Bunce. It
       uses FLUSH TABLES, LOCK TABLES, and cp or scp to make a database backup. It is a fast 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.

       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] groups of an option file. For information about option
       files, see Section 4.2.3.3, "Using Option Files".

       o   --help, -?

	   Display a help message and exit.

       o   --addtodest

	   Do not rename target directory (if it exists); merely add files to it.

       o   --allowold

	   Do not abort if a target exists; rename it by adding an _old suffix.

       o   --checkpoint=db_name.tbl_name

	   Insert checkpoint entries into the specified database db_name and table tbl_name.

       o   --chroot=path

	   Base directory of the chroot jail in which mysqld operates. The path value should
	   match that of the --chroot option given to mysqld.

       o   --debug

	   Enable debug output.

       o   --dryrun, -n

	   Report actions without performing them.

       o   --flushlog

	   Flush logs after all tables are locked.

       o   --host=host_name, -h host_name

	   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.

       o   --keepold

	   Do not delete previous (renamed) target when done.

       o   --method=command

	   The method for copying files (cp or scp). The default is cp.

       o   --noindices

	   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.

       o   --password=password, -ppassword

	   The password to use when connecting to the server. The password value is not optional
	   for this option, unlike for other MySQL programs.

	   Specifying a password on the command line should be considered insecure. See
	   Section 6.1.2.1, "End-User Guidelines for Password Security". You can use an option
	   file to avoid giving the password on the command line.

       o   --port=port_num, -P port_num

	   The TCP/IP port number to use when connecting to the local server.

       o   --old_server

	   As of MySQL 5.5.3, mysqlhotcopy uses FLUSH TABLES tbl_list WITH READ LOCK to flush and
	   lock tables. Use the --old_server option if the server is older than 5.5.3, which is
	   when that statement was introduced. This option was added in MySQL 5.5.3.

       o   --quiet, -q

	   Be silent except for errors.

       o   --record_log_pos=db_name.tbl_name

	   Record master and slave status in the specified database db_name and table tbl_name.

       o   --regexp=expr

	   Copy all databases with names that match the given regular expression.

       o   --resetmaster

	   Reset the binary log after locking all the tables.

       o   --resetslave

	   Reset the master.info file after locking all the tables.

       o   --socket=path, -S path

	   The Unix socket file to use for connections to localhost.

       o   --suffix=str

	   The suffix to use for names of copied databases.

       o   --tmpdir=path

	   The temporary directory. The default is /tmp.

       o   --user=user_name, -u user_name

	   The MySQL 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
