Challenge

After reformatting the Resilient File System (ReFS) volume at 64k cluster size Veeam fails to build Synthetic Full or Grandfather-Father-Son (GFS) restore points while incremental restore points created just fine:

Synthetic full backup creation failed Error: Agent: Failed to process method {Transform.CompileFIB}: The request is not supported. Failed to duplicate extent. Target file: <Backup repository name>\<Backup job>.vbk, Source file:<Backup repository name>\<Backup job>.vib, TgtOffset: 4091998, SrcOffset: 41019571928, DataSize: 42

Cause

Veeam B&R does not detect updated cluster size automatically.

Solution

Please go to the Backup Repository tab, right-click on the repository -> Properties and  go through the wizard to the end. Once it's done the cluster size will be updated in Veeam B&R database.
