Hyper-V virtual reverted to over a year old version
Posted on 2015-02-22
I have a Windows Server 2008 Standard server running Hyper-V.
All was good until we had a power outage the other day and my UPS batteries were not holding a charge for long (shame on me for not checking). The servers powered off instead of being shut down. I powered them all back on and things looked OK, until I realized 1 of my virtual servers reverted back to over a year ago.
The program I had installed is still there and my credentials log me in, so I thought the program was running fine. Now, I realize the data on that server is over a year old.
I've setup a number of Hyper-Vs and things have been working great, but I haven't had to do any real troubleshooting on an issue like this.
Any help in determining how this might have happened and, especially, recovering my virtual is greatly appreciated. I would restore it to a current state, but this virtual is running my backup software, so I have nothing to restore.
