Umbrel Personal Server Mirror/Backup/RAID?

Hey, is there like a straightforward way to mirror or RAID or something like that for all of the data on my node EXCEPT the bitcoin blockchain? I.e. if I also use my node as a picture server, bitwarden server, etc, I would like to mirror that data for redundancy.

The most straight forward way is to buy a NUC, NAS or server with hardware raid.
