NAME         top

       mariadb-hotcopy - a database backup program (mysqlhotcopy is now
       a symlink to mariadb-hotcopy)

SYNOPSIS         top

       mysqlhotcopy arguments

DESCRIPTION         top

       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

           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

           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

       •   --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

       •   --old-server

           Connect to old MySQL-server (before v5.5) which doesn't have
           FLUSH TABLES WITH READ LOCK fully implemented..

       •   --password=password, -ppassword

           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.

       •   --port=port_num, -P port_num

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

       •   --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

       •   --resetmaster

           Reset the binary log after locking all the tables.

       •   --resetslave

           Reset the 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 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
