I’m trying to plan a better backup solution for my home server. Right now I’m using Duplicati to back up my 3 external drives, but the backup is staying on-site and on the same kind of media as the original. So, what does your backup setup and workflow look like? Discs at a friend’s house? Cloud backup at a commercial provider? Magnetic tape in an underground bunker?

    • Primary ZFS pool with automatic snapshots
      • Provides 3+ copies of the files via snapshots (3)
    • Secondary ZFS pool at a different location replicates the primary
      • Provides more copies of the files (3)
      • Provides second media (2)
      • Is off-site (1)

    Does this make sense?

      I don’t think this meets the definition of 3-2-1. Which isn’t a problem if it meets your requirements. Hell, I do something similar for my stuff. I have my primary NAS backed up to a secondary NAS. Both have BTRFS snapshots enabled, but the secondary has a longer retention period for snapshots. (One month vs one week). Then I have my secondary NAS mirrored to a NAS at my friends house for an offsite backup.

      This is more of a 4-1-1 format.

      But 3-2-1 is supposed to be:

      • Three total copies of the data. Snapshots don’t count here, but the live data does.

      • On two different types of media. I.e. one backup on HDD and another on optical media or tape.

      • With at least one backup stored off site.
