Product Version

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. | Type | Timestamp | Log |
| * | ... | ... | ... |
| * | 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" |
| * | erro | YYYY/MM/DD hh:mm:ss | [ ... ] "[Error]" |
| * | ... | ... | ... |
Cause
This issue will occurs if the network shared temporary volume configured for the backup set is not NTFS formatted.
The volume selected for temporary location must be formatted NTFS 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 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 file format.
