Basically title. I’m in the process of setting up a proper backup for my configured containers on Unraid and I’m wondering how often I should run my backup script. Right now, I have a cron job set to run on Monday and Friday nights, is this too frequent? Whats your schedule and do you strictly backup your appdata (container configs), or is there other data you include in your backups?

    I use Duplicati for my backups, and have backup retention set up like this:

    Save one backup each day for the past week, then save one each week for the past month, then save one each month for the past year.

    That way I have granual backups for anything recent, and the further back in the past you go the less frequent the backups are to save space

    I run Borg nightly, backing up the majority of the data on my boot disk, incl docker volumes and config + a few extra folders.

    Each individual archive is around 550gb, but because of the de-duplication and compression it’s only ~800mb of new data each day taking around 3min to complete the backup.

    Borgs de-duplication is honestly incredible. I keep 7 daily backups, 3 weekly, 11 monthly, then one for each year beyond that. The 21 historical backups I have right now RAW would be 10.98tb of data. After de-duplication and compression it only takes up 407.98gb on disk.

    With that kind of space savings, I see no reason not to keep such frequent backups. Hell, the whole archive takes up less space than one copy of the original data.
