摘要：
A method and system for restoring a version of the data object from a continuous data protection (CDP) engine without being required to access the CDP engine via a separate CDP-specific interface. A data access request includes a data identifier and a metadata portion and is sent to a system layer, where the data identifier identifies a current version of a data object, and the metadata portion identifies a prior version of the data object to be retrieved specifically from the CDP engine. The prior version of the data object is retrieved from the CDP engine and returned for efficiently restoring the prior version of the data object.
