MABS – An Unexpected Error Occurred While the Job Was Running (ID 104)
This is going to be a quick post as fortunately it was a quick fix. One of our clients had a new MABS job setup and the System Protection components of the MABS backup were repeatedly failing. The C: and D: drive backups were working without any problem. The error message was:
“An unexpected error occurred while the job was running (ID 104)”.
There was no indication on the server itself as to why the job was failing, nothing in the event logs to indicate any VSS errors or anything like that.
It turns out that the server hadn’t had the Windows Server Backup feature installed. I installed that feature and the job started running, no reboot required.
