Error 404 Cannot Open File smb (-2 The system cannot find the file specified.)

Dear Friends,
We having StorageCraft Shadow Protect installed and we found that backups are getting failed.
The Error saying Cannot open the file.On all our jobs we see strange names for the backup files,
i.e. C_VOLC_VOLC_VOL-b001.spf (-2 The system cannot find the file specified.)
E_VOLE_VOLE_VOL-b001.spf (-2 The system cannot find the file specified.)
It should be C_Vol-b001-spf and E_VOL-b001.spf.

To resolve this you must follow below steps:-

1) Open the Registry (Start > Run > Regedit)
2) Navigate to HKLM\System\CurrentControlSet\Services\ShadowProtectSvc\Parameters\Job
Open the GUID , you will see Tasks, under takes you have for each volume a individual GUID
On the right side check the Key
DiffGenImage
If the Value is like: C_VOLC_VOLC_VOL-b001.spf is wrong
Change it to
C_VOL-b001.spf ( of course the complete path) 

You need to check this for all volumes.

3) After this not forget to restart the ShadowProtect Service.
Run the incremental backup now

It will work now.

Let me know if you have any questions.!!

Thanks
Pankaj
