Abstract
A computer-implemented method may create a first full backup of a set of data units at a first point in time. The method may create, at a second 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. The method may determine, based at least in part on the representation of one or more data units that have been modified since the first point in time, 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 second point in time. The method may use the difference to update the first full backup to a second full backup that comprises modifications made to the set of data units between the first and second points in time.
