    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 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 (oq~cq):

    shell> mysqlhotcopy db_name./~regex/
    

    mysqlhotcopy supports the following options:

    *
    --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 hostname 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).

    *
    --noindices

    Do not include full index files 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. Note that the password value is not optional for this option, unlike for other MySQL programs. You can use an option file to avoid giving the password on the command line.

    Specifying a password on the command line should be considered insecure. See Section 7.6, lqKeeping Your Password Securerq.

    *
    --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 the connection.

    *
    --suffix=str

    The suffix for names of copied databases.

    *
    --tmpdir=path

    The temporary directory. The default is /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, the RELOAD privilege (to be able to execute FLUSH TABLES), and the LOCK TABLES privilege (to be able to lock the 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
