Hello everyone!

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!

Thanks for your help !

    I wrote a bash script a while back that uses sshfs to mount an ssh server to the filesystem, then uses dd to write /dev/mmcblk0 to it as hostname-date.img and finally unmount the ssh server. Cron job runs that daily.

    I run that on each of my rpis. (just one rn, but theres been as many as 4 going).

    Any time I have an issue, be that my fault or not, I can just pull the sd card and write the last .img to it directly.

    There’s some extra stuff in there too: it checks for the dependancy sshfs and installs it if missing (for deploying to a new system without reconfiguring), cleans up backups older than x days, logging, and the ability to write the log file as a test instead of the whole filesystem.
