My daughter has a new iMac and has a .Mac account. She is looking at backup strategies. Wiill backup 3 copy from a burn folder to one DVD, when that is full continue on a second one and continue this until the backup is done(span it)? Fresh out of the box it is over 16 GB--5 DVDs or 3 DL. -- Ray Bowler rbowler.home.mchsi.com
