I'm setting up Windows Server 2008 R2 backup for the first time. When I try to do a test backup, it fails almost immediatly with the following error message.

It is failing in the Hidden Partition that Windows creates to store WinRE files and bitlocker data. (I don't have bitlocker installed).

I would skip backing up this partition, but Windows insists that it needs it for Bare Metal Recovery. Does anyone have any suggestions on fixing this?

Thanks, Daniel

Just wanted to let everyone know how I solved this problem.

It turns out the problem was with my backup drive. It was an external drive connected to the server with an eSata cable. The drive kept dissapearing from the storage manager during backup. I found other people complaining about eSata connections being finacky on google as well. So I switched to a USB 3.0 external hard drive, and it worked flawlessly! It backed up about 350 gigs in just over an hour.

Hope this helps someone else, Daniel
