I've had a couple of SBS 2011 boxes freeze randomly. This freeze always occurs when the installed backup technology (Backup Exec or Shadowprotect) kicks off.
Doing some diggin I noticed that in SBS 2011 there is a 'backup' that occurs every hour, on the hour and lasts for 10 minutes. I suspect that the VSS fight that goes on between the two backup techs is what's causing the server to freeze, so I've changed my installed backup schedule to be on the half hour.
But what IS this backup? It's not in scheduled tasks, nothing appears in the custom backup logs, it's not configured in Windows backup, sharepoint, anwhere. All I get is an event on the hour int he Application log saying 'brick level backup started' and then one ten minutes later saying it's stopped.
It's also not on on the Windows 2008 R2 servers I've built so it's definately a Small Bizo thing.
So: what is it? How can I stop it?
