Where system and data protection are concerned, I'm a belt-and-suspenders guy. I like to have multiple levels of redundancy. My primary backup method is full disk images with ATI 11, but I also wanted a file-based backup method to save user files in their original format. I just installed Microsoft SyncToy v2.0 Beta into Vista, and I'm really impressed with it. SyncToy v2.0 can be set to do simple backups from HD to external drive or to networked devices, which is called "echo", or it can synchronize both data sets, or always just add to the external set. It has many configurable options. With command line parameters, it can be set to run silently and can therefore be run as a scheduled task or, in my case, via a shortcut. It can also be used to synchronize data on multiple PCs across a network. I have it set that when I launch a shortcut, SyncToy checks for changes to the original data set and then makes those same changes to the external backup. Changes include additions, deletions, relocations, renames, etc. Because it writes only the changes, its operation is fast. It's compatible with Vista and XP. While v2.0 is, according to its developers, quite stable and its beta status has more to do with the unreleased status of a framework, if you prefer to use only stable releases you can get SyncToy 1.4. 1.4 has less functionality though. SyncToy v2.0 is an excellent tool, and its interface is clean and organized. It's amazing that MS would just give it away for free. I recommend it if you're seeking a nice free file-based backup or synch tool as an adjuct to your ATI images.
