Is it possible to restore old shadow copies? I'd really appreciate some help, as I'm in a lot of hot water. Basically I did an accidental delete of a bunch of folders on my client's server (server 2008, not R2). The next day I realized my mistake and stared using the "restore previous versions" feature to restore the files I had deleted. This was going well until the server restarted itself. When it came back up it was missing all previous versions. 
This was a bad time to find out that our backup hadn't been working, either. Our online backup is about a month behind schedule since there's so much data to back up. 
Is there a way to restore the previous versions files somehow? I have the drive locked from reading and writing currently. I've tried using data recovery software to restore deleted files but I've had limited success.

Thanks.
