I have a music library of 6.25 GB which I want to backup onto 2 DVDs. When I use Backup to get the files, the total size comes to 13.95 GB. Where did all the rest of the stuff come from?? Can anyone tell me what it is and whether I need it? If I don't, how do I get rid of it? Thanks. I've noticed when searching for this topic that a few people have had problems restoring stuff using Backup. I did a full 'Backup-backup' a couple of weeks ago only for it to tell me, at the end of the last DVD (one short of the number it said it would take), that the backup was incomplete.
