We have Windows 2012 Standard installed on a IBM server.
The Windows backup was working well until a few days back.
About a week back the backup failed with event id 517 and error code 0x80070005 or 0x807800C5.
VSS writers have no errors.
We have done the basics like checking the disks with sfc, formatting external storage, checking for viruses.
The wbadmin command returns following errors. Access is denied / The system can not find the file specified.
Kindly assist.
