Abstract:
Methods, software suites, and systems of generating a recovery snapshot and creating a virtual view of the recovery snapshot are disclosed. In an embodiment, a method includes generating a recovery snapshot at a predetermined interval to retain an ability to position forward and backward when a delayed roll back algorithm is applied and creating a virtual view of the recovery snapshot using an algorithm tied to an original data, a change log data, and a consistency data related to an event. The method may include redirecting an access request to the original data based on a meta-data information provided in the virtual view. The method may further include substantially retaining a timestamp data, a location of a change, and a time offset of the change as compared with the original data.
