Obbut

I have the same problem on Unraid 6.11.0. I'm using encrypted btrfs disks and am trying to do an encrypted Time Machine back-up and am unable to complete (or even start) a Time Machine backup. My logs look similar to those of the other users, it appears that the samba daemon is crashing. Without Time Machine encryption enabled, the backup does start successfully.
