You want to do online backup on the cheap? Well you dont really but just in case you think you do, here is how is is done and why you shouldn't.

Buy the cheapest online backup software available.
Dont actually backup the data, just mirror it.
Use a ridiculously low default retention period such as thirty days.
Dont concern yourself with fast restore. You might never need to restore much.
Dont familiarise yourself with the system. You can do that all on your own when you are in trouble.

You can see now how cheap online backup is done. Do you want it? Didnt think so. Any provider offering you free backup is prepared to treat your date with a level of respect similar to that of the above.

If you cant afford business level online backup, then you will have to do without it. Your offline methods are likely to be somewhat superior to the free online methods.
