Abstract: Systems and methods of coalescing and capturing data between events prior to and after a temporal window are disclosed. In an embodiment, a method includes determining a temporal window based on one or more of a user data and an automatically generated data, coalescing data between events prior to the temporal window using a processor and a physical memory and capturing data between events after the temporal window. The coalescing data between events prior to the temporal window may be determined by a set of overlapping operations to a data set, wherein certain operations have non-overlapping sectors which are not coalesced. Shifting a data view around a recovery point through a direction-agnostic roll algorithm that may use a roll-forward algorithm to shift the data view to a time after the recovery point and/or a roll-backward algorithm to shift the data view to a time before the recovery point.

Abstract: A method and system of tiered quiescing is disclosed. In one embodiment, a method includes generating a representation data of a multi-tier network, embedding a flag marker at a transaction event based on at least of an event data and a timing data, and quiescing, based on the representation data, a set of modules of the multi-tier network associated with at least one of the event data and the timing data using the flag marker. The representation data may be generated based on a transaction modeling of data flows between the set of modules of the multi-tier network (e.g., the set of modules may each operate in different tiers of the multi-tier network). In addition, a series of consistency points may be determined based on the transaction modeling of data flows between the sets of modules of the multi-tier network.

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 recover 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.
