摘要： 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.

摘要： 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.

摘要： Methods, software suites, networks, and systems of recovery point data view formation with generation of a recovery view and a coalesce policy are disclosed. In one embodiment, a network includes a virtualization module to form a data view around a recovery point, a recovery module to generate a recovery snapshot having an ability to position forward and backward from the recovery point when a rolling algorithm is applied, and an events module to generate a coalesce policy around the recovery point to reduce a storage requirement. The network may include an export module to transfer the data view to an external processing device as a virtual volume using one or more of an iSCSI and a fiber channel transport interface. The export module may automatically communicate the data view to a backup tape to provide extended data retention using a lifecycle management policy.
