After installing the Windows June 14,2022 update (KB5014702/KB5014746) on a Windows file server hosting SMB 3.0 shares, the follow Veeam Backup & Replication operations may be impacted:

• If those SMB 3.0 shares are added to Veeam Backup & Replication with the "Backup from Microsoft VSS snapshot" option enabled, the NAS Backup job(s) protecting those SMB 3.0 shares may fail with the following error:
  

  Failed to create a VSS snapshot Error: Failed to add volume [\\SMB3FS\SHARE1\] to the VSS snapshot set
  The given shadow copy provider does not support shadow copying the specified volume.
  --tr:Failed to add volumes to the snapshot set.
  --tr:Failed to perform pre-backup tasks.
  

• If those SMB 3.0 shares are used to store VMs for a Hyper-V host running Server 2012R2, the Backup job(s) for the VMs stored on those SMB 3.0 shares may fail with the following error:
  

  Failed to create snapshot (Fileshare Provider) (mode: Crash consistent) Details: Failed to add volume [\\SMB3FS\VOLUME1\] to the VSS snapshot set
  The given shadow copy provider does not support shadow copying the specified volume.
  --tr:Failed to add volumes to the snapshot set.
  --tr:Failed to perform pre-backup tasks.
  

When either type of job fails the following error will be found in the Windows Event Logs of the File Server hosting the SMB3.0 shares:

Microsoft File Share Shadow Copy Agent Error: The client connecting to the FssAgent RPC server did not have Local Administrator or Backup Operator privilege on this machine.
