How to send backups on multiple location? (lemmy.world)

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!

I ended up using rsync to do my backups. I have a laptop, an Android phone with Termux, a HomeAssistant docker image on a Raspberry Pi 4 and a home PieFed instance on a Raspberry Pi 5.

Each RPi board will create a complete backup on it's on storage. I'll then make a copy of each backup to my laptop. And finally another copy from my laptop to an external usb storage device. I also made a specific folder on my Android phone for the purpose of syncing with my laptop.

What I like about rsync is that it can be made to only transfer any changed files and not everything each time.

Since I use docker images on both my RPi boards, I made a script that shuts down all the containers before make a backup copy and finally starting the containers again. I even made a script to do something similar to restore from the saved backup.

Took a lot of trail and error to get them working but I am pretty happy with it. I have the scripts here if anyone is interested. I labelled what I did but didn't really leave comments explaining things. They are pretty simple anyways.

I could have used rsnapshot but learning how to use rsync has been interesting enough to me.
