If you’re looking for a place to backup some of your important files online, then head on over to Mozy.
Mozy lets you sign up for a free account with 2 GB worth of storage, which, while it might not sound like a lot, should be enough to back up at least SOME of your important files.
I signed up for an account, downloaded the Mac application, installed, and within minutes I was backing up my email (something I’ve been thinking about doing for a while).
I don’t know how often I’ll use Mozy, but it definitely seems like a handy utility.
