I am running SBS 2008 R2 as a virtual machine running under HyperV I have the USB backup drives running as Passthrough drives, and they are scheduled to be safely remove each morning, and re-mounted the next night before the backups.... this part is working as expected. The problem i am having is the backup runs for a few hours, and then fails when it gets to exchange as below: Log Name: Application Source: MSExchangeIS Date: 9/5/2011 2:55:50 AM Event ID: 9782 Task Category: Exchange VSS Writer Level: Error Keywords: Classic User: N/A Computer: PBSERVER1.pb.local Description: Exchange VSS Writer (instance cb5853bb-58dc-473d-a8fc-49a8fffdc5f2:53) has unsuccessfully completed the backup of storage group 'First Storage Group'.
