A computer-implemented method for creating reference-based synthetic backups. The method may include identifying a first set of references that identify data of a first backup. The first backup may represent at least a portion of a data set at a first time. The method may also include identifying a second set of references that identify data of a second backup. The second backup may represent changes made to the data set between the first time and a second time. The method may further include creating a synthetic backup that represents at least a portion of the data set at the second time by aggregating one or more references from the first set of references and one or more references from the second set of references. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for creating reference-based synthetic backups

A local host computer system creates a full backup image and one or more incremental backup images. The local host computer system transmits data from the full backup image and the one or more incremental backup images to a remote host computer system. The remote host computer system receives the data from the full backup image and the one or more incremental backup images from the local host computer system, and creates a synthetic backup image using the data from the full backup image and the one or more incremental backup images. In some embodiments, complete copies of the full backup image and the one or more incremental backup images may be transmitted to the remote host computer system. In other embodiments only the portions of the incremental backup images that are actually needed to create the synthetic backup image may be transmitted to the remote host computer system, and unneeded portions may not be transmitted.
