Abstract
A method and system of recovery point data view shift through a direction-agnostic roll algorithm is disclosed. The 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 after the recovery point and a roll-backward algorithm to shift the data view to a time before the recovery point. A data integrity is determined to be consistent at the recovery point by examining data and meta-data associated with the recovery point. The recovery point is associated with one of an automatically generated event, a user definable event, and/or a prepackaged event. A marker data is generated at the recovery point to enable the direction-agnostic roll algorithm to reduce a recovery time objective when an algorithm is applied.
