@indyj The file restore issue was due to installing XO on FreeBSD (fine for VM restores, not file extraction).

I then installed XO on Ubuntu 20, and this worked for restoring files from Linux VMs but not Windows VMs.
Then I installed on CentOS 8 and had the same problem as Ubuntu.

I then installed on Fedora 34 and everthing works fine.

@indyj The problem appears to be in the 5.15 kernel as well but the workaround seems to fix the issue.

You need to get the exact same structure ideally to not lose any data. But it's not a big deal, just copy/rsync whatever you like to the destination and that's it.

I don't this we support UFS right now.

If I remember correctly, we got:

FAT NTFS ext xfs LVM based
