I have a server running windows server 2003 with a usb harddrive attached to it that I use to backup my sever. I'm trying to figure out the best way to backup my server with the harddrive. First I did a normal backup because I read that you should always do one of these first. Next, I scheduled an incremental backup to run everyday and append the new data to the same backup file. The problem is every day around 1 gig gets added to this file. Eventually I'm going to run out of space. Is there a way to automatically purge data in the incremental backup file after so long. Or can I manually go into the file and delete backups (The daily backup appear individually in under the incremental backup file. I've done 3 or 4 so I have 3 or 4 "C" root folders inside of the incremental file.
