Free Online Backup/Storage: 2.5G *Limited Time Offer*

From now till November 30, 2008, Mozy will give you a free 2.5G account (as opposed to the normal 2G) if you use referral links--such as this one:

http://mozy.com/?ref=2QJV56

(After clicking on the link, scroll down to the bottom of the page and click on where it says MozyHome FREE: the "Sign Up" button at the top of the page is for the paid unlimited service. Alternatively, you can sign up without going through the link and put in the erferral code 2QJV56 when prompted.)

Mozy is owned by EMC (the storage company)--which means their services are reputable (your data are encrypted and protected). You can selectively choose what to backup (certain files/folders) if you have concern about privacy issues. You can selectively restore/download your backuped files via several means (including via the web). The response time of the service is reasonably fast. Check it out when you have a chance.
