I just upgraded the two hard drives I back up with Acronis 11. They are about twice as large now, although they contain the same amount of data as before, just a lot more unused space. Backups are taking A LOT long now, even the differentials run as a test right after a full backup. My question is, does size matter. Will the backup (I am running complete partition backups, not file backups) take longer if the disk is bigger or does Acronis 11 take into account that most of the disk is unused space? Thanks!!!!
