Hi there
Cloud is NOT viable for HOME users as a BACKUP system -- most people I know have Music / Video libraries of SEVERAL TB - now most cloud providers will possibly give a user say 50 GB -- by NO way good enough -- and in a lot of countries you STILL pay for broadbad bandwidth - you need an UNLIMITED usage for decent size backups and you need very fast broadband as well -- most people also forget that even with FAST download - upload can be up to 10X SLOWER !!!
Might not matter in uploading a few files to a file sharing site but uploading several HUNDRED GB will take a while !!!
I think businesses don't have to worry about this as they don't use "ISP's" in the classic sense - the larger companies also have dedicated line / cable systems.
The only time it might make sense as an individual is say you were a journalist and you needed to get pictures and your story out of for example N.Korea etc where normal email etc can't be relied on.

Where did those TBs of music and videos come from? Surely not original content by them personally. It's most likely either pirated, or purchased off some service like iTunes, Amazon, etc. so why would they need to back that up? Back it up locally if you want, but there's no need to back that up to hosted storage. If your house is destroyed, are you really going to care about your TBs of ripped music? No, you're going to care about your finances, your family photos, etc. The ones that were just destroyed along with your pretty little NAS, if you didn't have offsite backups of some sort or another. Besides, there are multiple reputable backup services that offer unlimited or very high-limit storage, so your point about "50GB limit" is wrong. Sure, downloading it will take ages (Some places ship you disks!) but it's a lot better than it being gone forever, is it not?
