Connect to the corporate vpn and backup that way. If I would take my company owned laptop and backup to some non company owned service I'd be fired. Very few companies will allow anything like that and when they do its only trough company approved sites where they have the proper legal documents in place.
The example would only work for a small home office, not any larger business.

That example is the reason why I've recieved a dozen e-mails over the lats couple weeks from various companies letting me know that my e-mail address has been stolen from a marketing company called epsilon. When you send your date off to a third party you loose control.

Okaaaay...This thread is about backup for individuals (and small businesses I guess). Anyway, note that backing up to the corporate VPN (which you mentioned) is a form of online backup.

Except thats not what the thread was about, a few people turned it into that but it wasn't the original purpose

I was trying speak against it because there were so many that said basically you need to have an online backup no matter what, its kind of like when any thread about computers turns to "buy a mac".
Online backups have a place, they are not the be all end all to backups and won't fit everyone, but the current popularity of "in the cloud" has so many going that route even if it isn't a good fit for their environment or situation. I was trying to point out that fist of all online backups for a number of reasons do not work for me and second are not the answer for everyone.
I'm more self sufficient than most, I don't call a plumber, I don't pay someone else to change my oil, I don't pay geek squad to fix my computers, I don't pay someone else to do my backups, I don't rely on someone else to provide my food/shelter/water if the need should arise.
