I have written before about Mozy.com. It is an excellent off-site backup service for Windows XP and Macintosh OS X computers. Of course, frequent backups are critical to all genealogists, as well as to most other computer users. Everyone needs to make backups, and off-site backups are even better than something stored beside your computer.
Mozy.com is one of the best bargains around, storing up to two gigabytes of files free of charge. That's enough for a GEDCOM file of a few million individuals or for a few thousand scanned images, depending upon the compression method used. If you need more space, Mozy.com offers unlimited storage space for $4.95 a month. All backups are made across the Internet whenever your computer is online.

I depend on Mozy.com to protect my files on both Windows and Macintosh systems. What I like best about Mozy is that it is automatic: I don't have to remember to make backups. Whenever my system is connected online, Mozy automatically backs up all new or newly-changed files every couple of hours without human intervention.
Apparently, I am not the only one who likes this backup service. Now Time magazine has selected Mozy.com as one of the top 50 most useful websites of 2007. You can read Time's (brief) description at http://www.time.com/time/specials/2007/article/0,28804,1633488_1633608_1633639,00.html.
