Backup Exec job failure due to snapshot handle(CPS is integrated)

Getting the below error,

V-79-57344-34070 - AOFO: Initialization failure on: "<<path>>:". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot provider error (0xE0008516): Resources specified for snapshot do not have any valid data on them. Check if files were deleted or renamed.
Check the Windows Event Viewer for details.

When we checked at the backup destination of the CPS tool, it doesn't show up anyhing. May be the snapshots are deleted or being moved.

In the selection list of backup exec, Continious Protection Server is checked, but there is nothing inside it(Usually some Database and other few files should be there).

Any suggestions for it.
