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.

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.

Abstract: A method, system, and apparatus of minimizing configuration of changes in a fabric-based data protection solution. In one embodiment, a method includes configuring a switch such that a write request to a primary storage device is transferred through a virtual initiator in the switch to the primary storage device and to a secondary storage device, and configuring the switch such that a read request from the secondary initiator of a data in the primary storage device appears as though the read request is coming from a physical initiator rather than the secondary initiator (e.g., such that system protocol may be bypassed because the switch intercepts a response having the data from the primary storage device through a virtual target which uses the virtual initiator of the switch to communicate the data to the secondary initiator rather than the physical initiator).

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.
