I tried a full backup the other night and after 3 hours it was only at 15%. Needless to say I cancelled the backup... there is no way I would want to restore from a backup that takes that long (it is easier to manually transfer the files again).
I later jailbreaked and took a look at the iPad file structure. I think my backup problem is caused by all the comics I have in ComicZeal. I've transfer 6gb+ of 3k+ cbz comics, which ComicZeal unarchived into individual folders. This resulted in 70k+ images in my ComicZeal file share. Even though 6gb+ isn't that much data, 70k+ files take forever to backup.
