At my office we have a server for Windows Server 2003 on it. It has all the company files on it, a majority of which are not being used at any given time since there is really only 3-6 people in the office usually. The server is running painfully slow and I was asked to give it a nice clean reinstall. The problem is I don't know how to go about backing up the files. All of the computers are networked, I tried using Windows' Backup program but that takes about 6-8 hours to do. What I wanted to do was get all of the files onto another computer and temporarily use that to host the files so everyone can access them as they need. And then reinstall the server PC, move the files back and that'd be the end of it. Is there a way I can accomplish this during office hours? Or at the very least limit the time I need without anyone accessing the files?
