Cause

Solution

 1. Check the path to the drive image:

Start >Run -- then type in the path \\.pdvfs and select "Ok"

If an access error is received, the PdvfsService component is not able to present the file system view of the deduplication folder. A reboot of the server may be necessary to properly restart the PdvfsService component. Note that just restarting the service is not sufficient.

After the reboot, check again for access to the \\.pdvfs path. Then run the backup job again.

Please make sure to run Live Update and verify that Backup Exec is using the latest version and Hotfixes.

2. Additional Troubleshooting:

Rebooting the server only resolves the symptom of the problem. In order to gather information on the root cause of the problem, the Application Event log and Backup Exec crash dump directory should be searched to find evidence of Pdvfs.dll crashes.
