I started my romans with online storage back in the days of BeInSync. That was a nice product, thought it had some trouble working on a PC with 2 NIC - it only bounded to the first one, which might now be the one connected to the internet - so it didn't work.

Latly, we have more and more clients seeking an online backup/storage/sync applications, so We went to look around.

We are currently looking at Mozy.com , crabonite.com and SugarSync.com. Though we are still haven't finished the testing here are our initial recomendation -

Personal - carbonite.com -
This is a very easy and cost effective - gives you unlimited storage for a reasnoble price (go for the yearly).

Server - MozyPro - the ONLY online storage that can backup SQL server and Exchange (we use ourselves now... on this server!)

Personal - best choise (but more pricy) - SugarSync.com - gives you everything Microsoft live mesh would want you to have -

backup, sync, share, and the best thing - access your data from anywhere - even your iPhone/Android! you can even stream music and video to your device without needing to download them.

I will post more data later on this week, with more comperrison.
