Not to Mozy.
I have been using Mozy for around 6 months now and recently had to restore some of my files. Restoring was a HUGE pain. Also, I found that it had not backed up all of the files that I asked it to backup, causing me to lose some of my work. The whole point of having Mozy is to not need to continually back things up, but if you can’t rely on them, its not worth your time. Use Carbonite, their major competitor. Its better.
