    Automatic MySQL Backup Script

    I modified crouse's mysql backup script with some modifications and have been using it for a few weeks. It saved my tush yesterday, so I thought I'd share it.

    It stores backup files in the directory /var/backups/mysql that it automatically creates. It also only backs up if MySQL is running by checking for the lock file.

    The nice thing about it is that you don't have to specify the names of the databases. It figures it out by itself.

    Stick it in cron, and make sure you have enough space in /var !

    You run it like this:

    # mysql-backup <root-username> <root-password>
    The code looks like this:

    # Create the backup directory if it doesn't already exist
    if [ ! -d /var/backups/mysql ]; then
         mkdir -p /var/backups/mysql
    # Do backups
    if [ -f "$LOCK_FILE" ]; then
        # Do MySQL backups
        for i in `/usr/bin/mysql -B -u $1 -e 'show databases' -p$2 | /bin/grep -v Database`; do
            /usr/bin/mysqldump --opt -u $1 -p$2 $i | gzip > /var/backups/mysql/$i.`date --iso-8601`.sql.gz

    Perhaps we should add this to the Wiki?
    My crime is that of curiosity. My crime is that of judging people by what they say and think, not what they look like. My crime is that of outsmarting you, something that you will never forgive.

    OK, it's done! You can find it here.
