Any system admin accessing to a server is able to take a copy of any data stored (or even transiently present on its network interface) on it.

If he is a spy/robber, if he is corruptible or threatened... a third party will obtain this copy. For the main culprit this doesn't induce any risk (where is the evidence?). This is absolutely not as with your bank, for example, which cannot really steal money without you taking notice.

How serious people are willing to store confidential data on any rented or hosted server is completely beyond me. Then some of their competitors' proposals are "just a little bit" better than theirs', or seem to have a pretty good grasp on some R&D or customer database.

Many here work on some cloud thing, most are honest and some will be upset by my comment. This is not about you but about rotten fruits in the basket.
