IDrive online backup has a promotion that offers 2GB of completely free back up space with no restrictions and for only $4.95 monthly you get Unlimited storage, which is a very good deal that I wanted to pass on to my friends who are into these types of things.They have just launched an IDrive Online Backup for Mac that has the same storage options and prices as us Window users have available to them. I know a lot of Mac users who may find the website of Idrive.com/idrive-for-mac.htm useful and helpful if you have the need for it.
