Error EC8F17B7 along with Error ED800012: (CRC Validation) is invalid & Error E4F3000E: Snapshot failure while using Volume Shadow Copy Service

Hi

I am trying to backup a PC using SSR2013 (Desktop ed). I have created a custom backup job to run on schedule but the backup continuously fails. I find the following error in the event log afterwards:

Error EC8F17B7: Cannot create recovery points for job: Drive Backup of (C:\), (D:\).
 Error E4F3000E: Snapshot failure while using Volume Shadow Copy Service. Please check application event log for VSS errors. Error code: VSS_E_OBJECT_NOT_FOUND (-2147212536). (UMI:V-281-3215-6071)

After running the job manually, I find the following in the event log:

Error EC8F17B7: Cannot create recovery points for job: Drive Backup of (C:\).
 Error ED800012: The internal structure of the recovery point file (CRC Validation) is invalid, damaged or unsupported. (UMI:V-281-3215-6071)

I have been trying a few solutions found on the Symantec website regarding these errors, but have not received any good results. I have also not found a solution that relates to SSR2013...

Thanks
