Hi lca77,
*phew*, you'r asking for a bit there...
Mozy is probably the best I can find that will get you what you want. They've been in the news as well, so quite popular. Have a look here -->
http://mozy.com. It is chargeable though but at only $4.95 per month for unlimited and
2GB FREE storage, that's not too bad. That way, you can 'try before you buy'.
Also have a look at
Wiki Upload. They're offering 5GB, so that's not too bad too.
Hope that helps.
Perhaps others can share more input?
