I am trying to use Backup to keep an extra copy of a large folder (about 1.5G) on my idisk. Backup works with other smaller folders, but not for this large folder. It seems to work fine, but when it finishes it just starts over again, and if I cancel it says "This plan has never been backed up to this destintation." Is there a size limit here other than the total 10G I am supposed to be able to use with my .mac account?
