Using windows xp pro
backup utility in system tools
My hard drive is 80 gig, but only has about 10 gig of space used up but when I back up to my external back up drive, the file is 35 gigs. Is this because of shadow copy? What settings can I use in windows backup to make the backup file the right size? There was plenty of space on the backup drive, but the backup timed out because of 'end of media' error.
