I, too, tend to be leery of online storage for some of the reasons listed above. The big players i.e. Google, M$, et.al. would not be an issue, it's the new kids on the block that you need be wary of. E.g. Some unscrupulous individuals can, and probably have, set up mirror sites to harvest such data, an example from my early days on the 'net I thought I'd check out what was on TV interstate (at the time the 10 network was not being broadcast to Darwin) So I typed in ten.com, thinking I'd get channel ten tv info, nope! It was a porn site. Only 'cause, in my ignorance, I was unaware of the difference that adding .au would make. It still happens, usually with financial sites, but there is no reason it cannot happen anywhere else. Obviously, if you are aware of the risks, and do maintain a good security regime, it is no less reliable than a good backup policy. FWIW, I take a risk with most of my program data in that if I lose it, it will be a nuisance, but nothing more. My critical stuff, I have a local backup and a copies stored off site (interstate, what's more).
