Your clickfree seems to come in three flavours: deluxe, basic and traveller. The first one uses encryption, and might give a problem to read your backed up data after reloading the OS. The last 2 should work, I think.
Curiously enough, their website only talks about backup and never about restore. That's an essential part of any backup solution. So to be sure I would use the phone support mentioned at http://www.clickfree.com/
There are tragic stories here in the forum of people backing up everything to an external hard drive to reload there OS, only to learn that external drive failed at the critical moment (that's Murphy's law), so they lost everything despite having made a backup. So we recommend you backup your backup to another PC first. If that works, it should also work after reformattting on this PC. Kind of a pilot run.

Anyone, I have backed up everything on my desktop to my clickfree. Now,I would like to reload my entire operating system. Will my clickfree recognize my desktop after the reload?
