I remember at my school, they were running a Novell network and on network drives, you had the option of salvaging deleted files using an interface, and purging them if they were no longer required. And best of all, it told you WHAT user deleted the file.
This system seemed really good, as a students deleted work was quick and simple to recover.
My question is, does anything like this exist in a Windows network? We have a staff member deleting files and we dont know who it is. It would also prove to be a handy solution for backup so us IT crew dont have to go up to the server room with tapes all the time.
