I administer a Windows Server 2008 box. For the past few weeks, our backups have only sporadically worked. Event Viewer and errors within WSB tell me that something is happening during the Shadow Copy phase of the backup. It appears that the Storage MiniPort Driver cuts out during this time and that's what's causing the backup.
There have been no changes made to the machine prior to this happening. We actually have Shadow Copy turned off on this server, so there's really nothing there to back up. Is there a way to turn this part of the backup off? Should I be looking more at the Storage Miniport Driver?
I found a link that suggested upping the limit of time the backup attempts to create a Shadow Copy before it times out. I'm currently attempting my first backup after making that change.
