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 dont use volumes at all and instead use bind mounts so i can just back up those folders
Use XFS as file system and use --reflink when you copy the volumes, creates an instant CoW copy no matter how big the folder is. You can then move, copy or whatever that folder to anywhere, or use a VM and simply backup the VM.
Nop, docker volumes bring me anxiety since I have no clue where are the files located. I always go with directory binding, I retain full control, master of my files, captain of my soul.
I use restic. Stop the container, run backup, start container. you can script it to run every night or something.
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
No. Any database in the last 20 years supports WAL, this advice is straight out of 2005
