MYSQLHOTCOPY(1)              MySQL Database System             MYSQLHOTCOPY(1)




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 LOCK TABLES, FLUSH TABLES, and cp or
       scp to make a backup of a database 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 ISAM tables. It runs
       on Unix, and as of MySQL 4.0.18 also on 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:

       ·  --help, -?

          Display a help message and exit.

       ·  --allowold

          Do not abort if target exists (rename it by adding an _old suffix).

       ·  --checkpoint=db_name.tbl_name

          Insert checkpoint entries into the specified db_name.tbl_name.

       ·  --debug

          Enable debug output.

       ·  --dryrun, -n

          Report actions without performing them.

       ·  --flushlog

          Flush logs after all tables are locked.

       ·  --keepold

          Do not delete previous (renamed) target when done.

       ·  --method=command

          Method for copy (cp or scp).

       ·  --noindices

          Do not include full index files in the backup. This makes the backup
          smaller and faster. The indexes can be reconstructed later with
          myisamchk -rq for MyISAM tables or isamchk -rq for ISAM tables.

       ·  --password=password, -ppassword

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

       ·  --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.

       ·  --regexp=expr

          Copy all databases with names matching the given regular expression.

       ·  --socket=path, -S path

          The Unix socket file to use for the connection.

       ·  --suffix=str

          The suffix for names of copied databases.

       ·  --tmpdir=path

          The temporary directory (instead of /tmp).

       ·  --user=user_name, -u user_name

          The MySQL username to use when connecting to the server.

       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:

       shell> perldoc mysqlhotcopy
