Encryption in the cloud is probably the way to go, but if I were running a business, and even just as a private individual, I'd still be concerned about exposure to risk either of data loss or compromise. As I'm sure everyone reading this is already aware, security is about more than just encryption algorithms. Ultimately it's a judgement call as to how secure and reliable you consider your local network to be in relation to the prospect of handing your data over to someone you don't know to store in an unknown location under unknown conditions with unknown levels of access by unknown individuals. Also, even if off-site storage is totally secure there is always the risk of your data being held to ransom at some point in the future. The cloud hosting company can arbitrarily decide to increase their administration fees at any time, and if most of your data is entrusted to them then you may have little option but to pay up (the "stand and deliver" business model).
