I have 3 servers:

  • my house
  • my sister house
  • my parents house

My server has a lot of services (Nextcloud and Immich the ones that use more space), the other 2 servers only have Home Assistant, Frigate and some shared folders. On my server I use Backrest to backup locally and on Wasabi, the other 2…well…are not backed up 🙈 …yet!

I was thinking to buy a couple of 14/20TB drives and install them in my parents and sister servers so that each server can backup data on the other 2. The backup will be done locally on all the servers with Backrest. How do I copy the backups across servers? Should I use Syncthing or is it better to use one repository per location on each Backrest? Or…other ideas?

Thanks!

    As for the other question in thr post: If you are using btrfs or zfs I believe both of those have a send function that operates at a block level and will only send block changes rather than full file changes
