Abstract:
1. A computer-implemented method, at least a portion of the method being performed by a computing system comprising at least one processor, the method comprising: creating a first backup of a set of data units at a first point in time; creating, at a subsequent point in time, a representation of one or more data units in the set of data units that have been modified since the first point in time; creating, based at least in part on the representation of the one or more data units that have been modified since the first point in time, a delta that represents a difference between a state of the set of data units at the first point in time and a state of the set of data units at the subsequent point in time, wherein the delta comprises: using the delta to update the first backup to a subsequent backup that represents the state of the set of data units at the subsequent point in time, wherein using the delta to update the first backup comprises updating the data units in the first backup with the at least one data unit that was not present in the set of data units at the first point in time and was present in the set of data units at the subsequent point in time.
