Pi NAS for multi-location backups (sh.itjust.works)

Over the past few months I've been thinking about what would be the best way to help me and my parents improve privacy and data storage.

With all the posts with cluster PC's recently, I'm wondering if the best option is to make a couple of NAS's with Raspberry Pi's with RAID, keep one at my place and another at my parents' house, and syncing their data with 2 private folders: one for myself and one for my parents.

But that opens up a few more questions. How to sync the data to match? Syncthing? Kubernetes? Should I go ahead and add Nextcloud to the Pi's? Should I make the Pi's expandable so other services can be added later, or plan to hook up a separate Pi to handle that? What else could I be missing?

This would be a great use case for ZFS. You can use dataset replication to sync the data. I’ve been very happy with TrueNAS but I think it only became recently available for the Raspberry Pi so not sure I would recommend it but I think you could use ZFS. You can use RAID-Z too if you multiple drives. The only limitation you might encounter is memory since ZFS is a bit of a hog. On the plus side though, ZFS should protect against bitrot if you’re worried about that.

ZFS doesn't really hog memory, rather it consumes almost all available memory as cache. But it frees it as soon as it's needed.

If you go the ZFS route, you could check out syncoid.

Some other tools that might be worth considering (that aren’t related to ZFS) are borg and restic.

Hope that helps.
