[[6.10] TimeMachine backups continue to fail "failed to attach using diskimages2" "operation not supported by device"]

I solved this issue adding these lines to the SMB Extras:

[Global]   
   vfs objects = catia fruit streams_xattr
   fruit:nfs_aces = no
   fruit:zero_file_id = yes
   fruit:metadata = stream
   fruit:encoding = native
   spotlight backend = tracker

 

[[6.9.0 Beta 29] whole cache drive is public]

Thanks.

Seems like the update enabled the disk share for the cache drive.

I found the disk share scrolling down at shares and set it to private again.
