I've been playing with this because wanted so bad this to my setup and think that made it work. At least have been running this for some weeks and didn't found any issue so far.
My setup is a Raspberry Pi 5 that just runs Minarca server and the data is stored on 2 SSDs in RAID10. For clients currently have 2 Raspberry Pi 5, one with K3s server (to backup the K3s token and db) and another that acts as a NFS server with 4 SSDs in RAID10 (where i'm backing up data from my Nextcloud, Vaultwarden and more).
There's still some work to do (cleaning up pipelines, document changes and keep the base code for Minarca up-to-date)
Added some print screens for fun
