@TJ,

Absolutely agree – backups without verified restores are just false confidence. Testing the restore process regularly is critical to ensure the backup is actually usable when it matters most. And yes, setting up email alerts from cron jobs is a simple but powerful way to catch silent failures early.

Thanks for the solid reminder — I’ll update the article to reflect these important points.

@Nole,

Thanks for the suggestion!

I’ve updated the article to include the rsync mirror option you mentioned, which is a great way to keep remote backups in sync.

You should create a mirror as well with something like rsync:

rsync -avz \
      -e "ssh -i $SSH_KEY -o StrictHostKeyChecking=no" \
      --delete-after \
      "$BACKUP_DIR/" \
      "$REMOTE_USER@$REMOTE_HOST:$REMOTE_DIR/"

Backups are good, and this script looks solid (though I haven’t tested it myself yet). But backups are only part of the solution. Backups can fail for various reasons. It’s the restore process that must be tested repeatedly to ensure the most recent backup is valid and that you can actually recover the data. Otherwise, you’re just burning compute cycles and wasting your time.

Also, if you’re running it through cron, make sure the results are emailed to you (or your team). That way, you’ll know it’s working or be alerted to any failures so you can investigate and fix them.

I recently switched to automating my MySQL backups using a Bash script with Cron jobs, and it’s been a game-changer! It’s an easy-to-follow, reliable method to ensure my databases are backed up regularly without any manual effort. Highly recommend this approach for anyone looking for a simple, automated solution.
