Ways to backup your docker volumes ? (alien.top)

I bought a second hand NUC to have a little more horsepower to run various services. I have it connected to my NAS, but almost all of the docker volumes reside on the SSD in the NUC.

It would be nice to be able to backup those volumes to my NAS in case the NUC fails. I have Debian 12 running on it.

What are my options ? Should I just backup my docker volumes or does it make more sense to backup the entire NUC ? (I'm less tech savvy then I might appear. Please be generous with your explanation, I still have a lot to learn)

I use zfs mirror 2x SSD for cache data snapshot no need to stop or restart docker 0 downtime and super easy and fast to restore data like 1 second and it's done

Be aware that databases might be corrupted by snapshots

No. Any database in the last 20 years supports WAL, this advice is straight out of 2005
