As per error reported in event viewer.( attached-capture2.png)

I ran following on EMS:

Didn’t find any issue with vssadmin list writers . In our case, the VSS writers were fine.

Typed: vssadmin list providers . This will show the VSS writers capable of taking a system snapshot when backing.
Next typed: disk shadow . Once that comes up typed: list providers . one will now see the hardware ID for each VSS writer that you have.

Took note of what VSS error said in your event log. For mine I noticed that a VSS writer with the ID of { 819e044d3..} was giving lots of errors. I matched up the ID number of the event log to the ID number of command prompt output. I noticed that the HW Provider was the culprit

My question is do we really require that writer from Commvault perspective?
