I have ditched cloud storage completely as it was costing way too much lately, everything has seemingly gotten more expensive nowadays…
I now have in my PC an nvme SSD and two 2TB enterprise hard drives, all formatted XFS
I am planning to get two more 6-8 Tb enterprise hard drives for archival purposes and a general mirror of everything. Not in a RAID, but me manually mirroring the more important files, to maximize storage.
Do I stick to XFS, or is is wiser to use Btrfs? If so, how would you suggest I format that future volume?
LE: Also, in theory, how can I protect a file system against file deletions, or to not delete more than one file at a time etc? Is there a better way than just mounting it read only?
