  Its the backups that save you from crypto malware.

    True, but I have yet to find a reason to prefer full (or even incremental) backups over CoW. Full backups are just too big and slow, and good reliable open-source and cross-platform incremental backup software is hard to find. I've found using Syncthing for Client-->NAS-->Off-site with BtrFS snapshots on both servers to be just perfect (of course, YMMV).

      > good reliable open-source and cross-platform incremental backup software is hard to find I've been using rsnapshot for at least a decade, and it's available wherever perl and hard links are available (which isn't windows, at least pre-WSL).
