Coalescing and capturing data between events prior to and after a temporal window

摘要

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.

1. A method of a storage network, the method comprising:
determining a temporal window based on at least one of a user data and an automatically generated data; coalescing backed up data in the storage network between events prior to the temporal window through a processor communicatively coupled to a physical memory to optimize storage space, the events including at least one of a system crash, a login failure, a configuration change, and an automatic backup operation of data in the storage network, and a recovery point also being tied to an event of the events; continuously capturing data between the events after the temporal window; and shifting a 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.
