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. |
