I am curious - what was it about Mozy that made you question the security?

Anyway, JungleBook/S3 also sounds like an intriguing option, and more than likely, fairly cheap, too. Thanks for the tip. ^

Edited to add: In case anyone was wondering, it is not possible to shut down the Mozy Backup application from within the application. Just got the confirmation for Mozy CS, who said that the application is intended to provide "automatic backup". Well, if you are like me and have a couple of older computers, resources are precious! It seems silly to me that you need to have an app running 100% of the time if you only use it for a couple of hours each week.

If you care, you will have to do what I do, and use Task Manager to shut down the application manually.
