VRH On-demand, fine-grain, incremental-integration of on-site storage content with remote compute and storage resources method, system, and apparatus

摘要

A remote accessor apparatus captures a state of an existing data store and exports the state to a hosted projected data store. When a file operation interceptor apparatus receives a request, it determines whether it requires a transmission from the existing data store or it can be fulfilled locally. An operation controller combines local and transmitted data to fulfill the requested file operation and stores the difference locally. On-demand, read/write requests are intercepted and fulfilled by a combination of locally provisioned file content operations and remote access requests to the agent apparatus in whole or in part. Upon first request, file contents are transferred to meet application need but are then retained for other users and other uses. Upon request, a new state for the existing data store is provided by combining archived data with local file operations.
