How to roll back an "accidental" backup?

[Uth]

Nooooo! Blue screen in the SBS 2008 after a power failure and after some time and a lot of stress from the management, I sort of panicked and in the SBS DVD I chose the repairfunction and did a back up from the raid (the only one I could see) from the 30th of November at 02.00. What I didnt see was, that the back-up was from the 30th of November 2009...I know...unforgiveable. But now its done...

Is there any way one can roll back such a back-up - which has turned out to be a regular disaster? Please... !!!
