Sure, i've used a couple of upload sites recently to transfer large files... but never anything that was actually important, i didn't have local backups of or couldn't be easily replicated.

I've read about people trying to get their files back off the servers and all the other hoo-ha going on, and have nothing against people trying to do that or using the excuse that it was their main backup... just seems extremely silly to rely on it form my point of view. It's not possible to rely on Google, for fear of them shutting down your account for some violation or T&Cs (and no recourse for appeals), so to rely on these kinds of companies...

Not sure why I got down votes for a genuine question.
