Abstract:
A method and system of recovery point data view shift through a direction-agnostic roll algorithm is disclosed. In one embodiment, a method includes forming a data view around a recovery point, and shifting the data view around the recovery point through a direction-agnostic roll algorithm that uses at least one of a roll-forward algorithm to shift the data view to a time before the recovery point and a roll-backward algorithm to shift the data view to a time before the recovery point. A data integrity may be determined to be consistent at the recover point by examining data and meta-data associated with the recovery point. The recovery point may be associated with at least one of an automatically generated event, a user definable event, and a prepackaged event. A marker data may be generated at the recovery point to enable the direction-agnostic roll algorithm to reduce a recovery time objective when an algorithm is applied.
