MUSI After much research and demoing, I bought this over a month ago. This app is really fantastic and makes for very easy and customizable backups. I particularly like the fact that it does not require you to do disk images, restore, etc. You just set a hard drive as the backup device, then drag into the main window the items or folders you want to back up. It keeps those items (and any new items you later add to the list) associated with that particular hard drive, so you can just click and backup. You can add a whole new different list of items you want to back up to a different hard drive, thereby having multiple backup sets. You then choose any hard drive from a popup list, and the items list changes according to the hard drive chosen. Very cool.
SmartBackup operates like a true backup by only copying the changed files. It also archives the previous and deleted versions so you never lose anything.
Asthetically this app has a beautiful GUI, and I love the darkened "window shade" that drops down when it is working. Nice touch.
I do alot of research and demoing before I part with my money. SmartBackup easily beat out every other contender, hands down. I highly recommend it.
