Description:
Challenge
A NAS backup/file to tape job skips VSS snapshot creation on SMB share and ends with the following message in the log:Failed to create a VSS snapshot for %hostname%, failing over to backup directly from the share.
Solution
Requirements Below are the requirements for VSS to function when backing up from an SMB share hosted by a Windows File Server.: The Veeam Backup Server and the Windows File Server hosting the SMB Share must be running Windows Server 2012 R2 or later. The Veeam Backup Server and the Windows File Server hosting the SMB Share must be joined to the same Active Directory domain. The “File Server VSS Agent Service” role service is enabled on the Windows File Server hosting the SMB Share. The backup agent runs in a security context with backup operators or administrator privileges on both the Veeam and File servers. The backup agent/application runs in a security context that has at least the READ permission on the file share data that is being backed up. Veeam Backup Proxy server should resolve both hostname and IP address of Windows File Server hosting the SMB Share. For more information on the VSS for SMB File Shares feature, see the following Microsoft page: https://docs.microsoft.com/en-us/archive/blogs/clausjor/vss-for-smb-file-shares
