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 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 one of an automatically generated event, a user definable event, and/or 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.

Abstract: Ensuring data persistence and consistency in enterprise storage backup systems method and apparatus are disclosed. In one embodiment, a method includes creating a data log structure (e.g., a log file) on a storage device (e.g., a Serial ATA drive, a SCSI drive, a SAS drive, a storage are network, etc.) coupled to an application server to store a backup data generated by a filter module in a continuous backup environment and buffering the backup data generated by the filter module through a memory module that transfers the backup data to the data log structure on the storage device based on an occurrence of an event. The data log structure may be created by configuring a portion of the storage device as a dedicated resource available to the memory module to copy the backup data and the data log structure may be a file on the storage device coupled to the application server having the file system.

Abstract: 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.

Abstract: A method, apparatus, and system of a sequencing technique to account for a clock error in a storage area network are disclosed. In one embodiment, a system of a backup server includes a processing module to examine a data timestamped with a sequence of characters denoting a time according to a clock source, an analysis module to determine that the data has been timestamped at an earlier time than an other data previously received, a substitution module to provide the data an incremental sequence number placed with the data using an algorithm until a new data is received that includes a future timestamp with a later timestamp than the timestamp of the other data, and a storage module to store the data.
