When my Carbonite expires, I am going to Mozy for sure. I tried them once - way back when - and went with Carbonite because it finished backing up all my files sooner. At the time, they seemed exactly the same - that was before I found out about Carbonite's insulting customer service.

Plus, my brother is now an authorized Mozy seller. If you use this URL http://www.mozy.com/home/?ref=3f9a896b&kbid=45056&m=20&i=87 he'll get a few pennies and do whatever he can to help if you ever need it.
