I have been running Windows Server Backup on an SBS2011 server for quite some time. I backup selected files to an external drive. Today I installed a second external drive and performed a one time backup of Exchange to that drive.
The Exchange backup ran to completion and is accessible, however, I can no longer recover files from the daily backup I have been running to the first external drive. When attempting to recover, I get an error message indicating that the volume shadow copy on the destination drive is not accessible. I see the drives being backed up, but cannot drill down and recover. This is the case for current and all prior backups.
I'm assuming that this was caused by my running a single, one-time backup to the other drive, I have restarted the VSS service on the server, but that did not resolve the problem.
Are my old backups recoverable? I can see the VHD file on the external drive.
