I have 2 alternating external hard drives, in which I have one at home (drive A) & one offsite (drive B), I bring the offsite one home to backup the newer drive A contents to, so far I have used disk utility, & just copy the whole of hard drive A to hard drive B in an overnight backup, but these backups will take longer as I get more content.

Is there a mac app that can tell the new files on the home drive & copy just the new files to the offsite backup drive B? without me gong through disk utility or doing it by hand in finder?
