BackityMac is clever utility that offers pre-set, one-click settings for backing up your Mail, iCal and Address Book data into a disk image—see a previous post for screenshots and brief review.

An updated version was released on Saturday, making it even more useful than before.

It can now burn the image it makes to CD, DVD and Dual-layer DVD. Large images are segmented and spanned across multiple discs.

It will also ask for an administrator password before backing up a Home directory.

BackityMac also has pre-sets for iTunes, iPhoto and iWeb data, browser bookmarks and a full Home directory backup.

BackityMac is donation-ware and is available from the developer’s web site .
