Dears ,

We backup DAG exchange server 2010  Using backup exec 2010 R3 and updated With SP2  and  recent Hotfixes

The backup job backup the passive copy of the database .

 

The backup job is unstable , Sometime Succeeded and simetime failed with the following error related to VSS

  1. Exchange VSS Writer (instance b7912ba8-f300-417b-95ee-a42c19ec93e1:10) failed with error code -2403 when preparing for Snapshot.
  2. Exchange VSS Writer (instance b7912ba8-f300-417b-95ee-a42c19ec93e1:10) failed with error code 1295 when processing the post-snapshot event.
  3. Exchange VSS Writer (instance b7912ba8-f300-417b-95ee-a42c19ec93e1:10) failed with error code 1295 when processing the backup completion event.
  4. Exchange VSS Writer (instance 0ffb1558-aae8-4c1e-b49e-a81b72e392b1:10) failed with error code -2403 when preparing for Snapshot.
  5. Information Store (14908) Shadow copy instance 10 aborted.

 

We reboot the servers that are members of DAG but the job is still  unstable.

I hope to provide me with your ideas Why that happen ?

 

Thanks

It could be anything from corruption in the OS, to a faulty VSS writer, to a maintenance task that might be running at the same time as the backup job, to something else like VMware running a snapshot of a VM before BE backs it up...I think that VSS errors are something that can't be fixed due to the various issues that cause them...

Thanks!
