ATTENTION 1st January, 2022: v7 officially End-of-Life [details]
When perform a file backup up on AhsayOBM/AhsayACB v7 the job ends with
"Snapshot for Shadow Copy Set is missing, backup terminate." error.
No. | Type | Timestamp | Log |

The error message is returned by the Microsoft Windows Volume Shadow Copy Service (VSS).
To support backups of volume mount points on Windows file backup sets on AhsayOBM/AhsayACB v7, if "Volume Shadow Copy" option is enabled , AhsayOBM/AhsayACB v7 will initiate a VSS snapshot of all local drives found on the machine regardless if the drive has been selected in the backup source.
This behavior different from AhsayOBM/AhsayACB v6 which only initiates a VSS snaphot of a local drive selected in the backup source.
If the client machines are not configured with volume mount points and there are persistent
"[Shadow Copy] Snapshot for Shadow Copy Set is missing, backup terminate."
backup errors.
As a workaround you could consider reverting the current AhsayOBM/AhsayACB v7 VSS snapshot behavior back v6, this can be done by:
VSS, Volume Shadow Copy Service, volume mount point
