I have seen many online backup services, I choose MozyPro.  I backup my own computers with MozyPro, and have several clients that use the service.  They are very satisifyed.  I have one client that has over 350 Gigs of data stored with MozyPro.  I also like the Mozy product for home users.  It is very easy to use and the restores are very easy to get from the web site.  I have restored everything from a single file to entire directory’s with ease.  If you are in doubt about the safety of your data, and hackers, with Mozy and MozyPro, your data is encrypted before it leaves your computer, and the people at Mozy don’t have the key, only you have the key.  So if you have data that is important to you, Pictures, Music, Videos, or financial data, get backuped up now.
