I have a small OrangePi running some small services on it (some with Docker and some without Docker).
And I’d love to know how do you backup your single-board computers.
Do you just rsync the system to a storage server ?
Do you plug in a USB drive and rsync on it ?
Do you save only the important data or the whole system ?
For now my SBC is not backed-up and I’d like to get a good backup solution up and running quickly! (I don’t trust SD cards to last long…)
I have access to USB drives and disks and also another big server with 20TB of storage which I can make the backup to if needed!
The second isn’t a bad idea if it’s in combination with the first. Then you have an image you can restore with most of your config and you can just restore the rest from the normal backups.

There are options good and bad.
I’d back up just the dockers. The OS can be rebuilt easily enough. Yes Rsync the data
Or. Shut it down, pull the SD card, put it in another computer and rip it as an image, Full bootable backup
I would do the first not the second.
