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.
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.
