Challenge

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.
VSS Event Error

Solution

NAS Backup Job Failure

Review the following article from Microsoft:

Specifically:

  1. Ensure that the June 14, 2022 update is installed on the following servers:
  2. Check the share permissions within Veeam Backup & Replication to ensure that Veeam has been configured to use a domain account that is a member of the Local Administrator or Backup Operator group on the File Server hosting the SMB 3.0 Shares.

Hyper-V 2012R2 VM Backup Job Failure

Review the following article from Microsoft:

KB5015527: Shadow copy operations using VSS on remote SMB shares denied access after installing Windows update dated June 14, 2022

Specifically:

  1. Ensure that the June 14, 2022 update is installed on the following servers:
    • File Server hosting the SMB 3.0 shares.
    • Any Hyper-V Server 2012R2 host using those shares to store VMs.
    • The Veeam Backup Server.
  2. On every Hyper-V host that uses the SMB 3.0 shares as VM storage, update the Veeam Hyper-V Integration Service to change the Log On As from 'Local System account' to a domain account that meets the following requirements:
    • The domain account is a member of the Local Administrator group on the Hyper-V host.

      and
