I've used this app from 1.1.3 (maybe even 1.1.2), and have been very happy with it. It's not the most graceful looking thing, but I have it set up to run when I sleep; so I don't ever have to worry about it. I occassionally perform Boot-Up from my external FireWire drive just to test it out - never had a problem. Note: If you have a notebook and need to Boot from the external drive, make sure the Firewire is plugged directly in to the laptop.

It does its job, and best of all it is FREE. I even ended up buying 2 LaCie drives just because of this software. I figure if they give me something like this for free, I might as well patron them.

For someone who really needs a pretty and super simple interface, then I might suggest Super Duper. It is also a very easy program to use. It's just when I factor in that FREE part, it was a no-brainer for me.
