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 and NetWare.

       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.

       ·   --help, -?

           Display a help message and exit.

       ·   --addtodest

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

       ·   --allowold

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

       ·   --checkpoint=db_name.tbl_name

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

       ·   --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.

       ·   --debug

           Enable debug output.

       ·   --dryrun, -n

           Report actions without performing them.

       ·   --flushlog

           Flush logs after all tables are locked.

       ·   --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.

       ·   --keepold

           Do not delete previous (renamed) target when done.

       ·   --method=command

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

       ·   --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.

       ·   --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 5.3.2.2, “End-User Guidelines for Password Security”. You can use an option
           file to avoid giving the password on the command line.

       ·   --port=port_num, -P port_num

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

       ·   --quiet, -q

           Be silent except for errors.

       ·   --record_log_pos=db_name.tbl_name

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

       ·   --regexp=expr

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

       ·   --resetmaster

           Reset the binary log after locking all the tables.

       ·   --resetslave

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

       ·   --socket=path, -S path

           The Unix socket file to use for connections to localhost.

       ·   --suffix=str

           The suffix to use for names of copied databases.

       ·   --tmpdir=path

           The temporary directory. The default is /tmp.

       ·   --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
