My snapshot.backup.to.secondary is configured to ‘true’

The snapshot location 'snapshots/16/111/66210b31-7445-4586-89ea-52a37f5b1ab5’ 
for id=117 no longer exist. All of the concerned snapshots reference 
'snapshots/16/111/...' for location but but directory 111 no longer exist.  110 
and 112 exists.

Regards,
Antoine
