I've been using the program for over a year now and it has worked flawlessly. The more that both my digital photo and music libraries have grown, the more concerned I became with HD failure. I have scheduled backups to an extrenal G-Drive of my Tiger, iTunes, iPhoto and documents volumes. I don't even think about it anymore.

Only occasonally do I turn off my system update to ensure that when I do system upgrades I have a fallback if things go awry.

Congratulations and thank-you to the developers. If you are looking for reliable back-up software for a reasonable price, I highly recommend SuperDuper!
