A cloud based system includes a data network, a cloud host and a data center. A context database stores respective contexts of multiple virtual stores. A log database records transfers of content into and out of each virtual store. At least a portion of the context and log databases is encrypted by the data center. A transfer application executes on the cloud host and responds to a transfer request to transfer content from a virtual store by: retrieving the context of the virtual store from the context database; and forwarding the transfer request and context to the data center. The transfer application also responds to a load request to load content to a virtual store by: retrieving the context of the virtual store, and a log of transfers affecting the virtual store from the log database; and forwarding the load request, context and log to the data center. |
