NAME

    xtrabackup-helper.pl

MODES

    When running *xtrabackup-helper.pl* you can specify the mode with "-m" /

    "--mode" (default: "list").

    "list"

        Lists all backups (full and incremental) in an orderd list. The

        oldest backup is printed first (at the beginning / top), the most

        recent backup ist printed last (at the bottom / end). Indeted

        backups show an incremental backup which is based on the backup

        right above.

        Example listing:

            user@host# xtrabackup-helper.pl -m list

    

            2013-07-04_14-14-51

                2013-07-04_14-18-57

            user@host#

    "restore"

        Restores the a backup. If no "-r" / "--restore" is given, the most

        recent backup gets restored. Other (older backups) can be selected

        by the identifier / date from the "list" mode.

    "backup"

        Performs the backup of the database server. It does an incremental

        backup, except the following is true:

        *   There is no other full backup

        *   The current day of week (determined by "date '+%u'") is the same

            as the one given via "--full-day" (which defaults to 1 /

            monday).

    "update"

        The script loads the newest version of itself from github and

        replaces itself

    "weedout"

        Deletes old backups. See: "--keep-days".

OPTIONS

    "--mode", "-m"

        In which mode to run, see "MODES".

    "--dir", "-d"

        The base directory of the backups. It defaults to

        "/var/backups/mysql/data/". This dirctory must exist. "innobackupex"

        then puts its default directory structure in there, so one ends up

        with a subdirectory for every single backup.

    "--restore", "-r"

        Which backup to restore. Defaults to the most recent one.

    "--out", "-o"

        The directory where to restore to.

    "--chown", "-c"

        A user (or uid) and optionaly a group (or gid) to "chmod" all files

        in the "out" directory to. If both user and group are given, they

        need to be seperated by ":".

    "--force", "-f"

        If the "out" directory is not empty one can force a cleanup with

        this option. ATTENTION: all files in the "out" directory are

        deleted!

    "--full-day"

        The day of week when a full backup should be made. Defaults to 1

        which means monday.

    "--man", "--help", "-h"

        Displays this help / manpage.

    "--keep-days", "-k"

        This is the minimum of days in the past where it's possible to

        restore a backup from. defaults to 7. This means, that e.g. full

        backups can be older than this setting, because an incremental

        backup, which is younger is based on that full backup.
