samba - Sep 2018 - 4.8.5 + TimeMachine = Disk identity changed on every connect, cannot backup

Hi,

I configured Samba 4.8.5 on Debian (Buster)  with vfs_fruit as a TimeMachine
destination and while it detects it and does the initial backup to some extent
(30GB out of 200GB),
TimeMachine then fails with a message about the disk identity having changed.
Options are “don’t backup” and “backup anyway”. When using “backup anyway”, the
backup creates a secondary sparse image and starts from scratch, and won’t even
touch the existing sparse image.

	My Mac is running in VirtualBox. I have using latest beta Mojave. I only found
one person with same problem. I don't know if problem is in Mac or Samba.
If I use the same Mac over AFP backing up works.

	Regards  Dan

I spent two days looking for the solution. And yet I have  workaround. In first
time make backup with AFP. After this
you can stop AFP and switch to SAMBa and TimeMachine backup works.

     Regards
                     Dan

I found a problem. In Debian Buster is samba compiled without  
--enable-spotlight without this TimeMachine doesn´t
work. Recompile samba with  --enable-spotlight and all works.
