AhsayOBM Windows Backup Fails: Temp Location Must Be NTFS-Formatted

January 21, 2026

Product Version

AhsayACB / AhsayOBM: 7 and above

Operating System

Windows

Symptom

When performing a MS Windows System or System State backup, the following error message is displayed on the backup client interface, or in the backup report:

No.TypeTimestampLog
*.........
*info...[ ... ] "The operation ended before completion."
*info...[ ... ] "A backup cannot be done to a remote shared folder which is not hosted on a volume formatted with NTFS/ReFS"
*erroYYYY/MM/DD hh:mm:ss[ ... ] "[Error]"
*.........

For v10.1.6 and above, this is the error message displayed:

  • If the temporary location is on a local drive.

    Error on Local Drive

  • If the temporary location is on a network drive.

    Error on Network Drive

Cause

This issue will occurs if the network shared temporary volume configured for the backup set is not NTFS/ReFS formatted.

The volume selected for temporary location must be formatted NTFS/ReFS because Windows Server Backup uses shadow copies to maintain backup versions.

Resolution

To resolve the issue, convert the corresponding hard disk or partition to the NTFS/ReFS file format (https://technet.microsoft.com/en-us/library/cc730863.aspx).

Alternatively, modify the temporary location for the backup to another volume that is in NTFS/ReFS file format.
