1. A method, comprising:
receiving, by a computing system, a request to restore a specific backup instance of a volume of a recipient system to the recipient system;
tracking, by the computing system and at the recipient system, changes that have occurred to the volume of the recipient system since a previous backup snapshot, wherein the previous backup snapshot occurred at a first point in time;
restoring, by the computing system, data associated with the specific backup instance to the recipient system from the computing system at a second point in time; and
performing, by the computing system, a constructive incremental backup snapshot by excluding a first set of one or more changes that occurred at the recipient system between the first point in time associated with the previous backup snapshot and the second point in time associated with the specific backup instance being restored to the recipient system and including a second set of one or more changes that occurred at the recipient system after the second point in time associated with the data associated with the specific backup instance being restored to the recipient system.
