I use mergerfs to pool a bunch of varying sized drives and then run snapraid on the whole pool to protect it. Then, I’ve got Kopia backups running and backup up to a remote repository. This solution has been flexible and I’ve already been able to recover from 2 drive failures very quickly and easily.
