Abstract

Techniques described herein relate to a method for generating synthetic full backups. The method may include obtaining a snapshot associated with a previous backup stored in a data domain; obtaining a second snapshot associated with a current state of the source data; generating a snapshot difference report using the first snapshot and the second snapshot and including a delete list, a rename list, and a copy list; storing a copy of the previous backup in the data domain; performing a delete operation on the copy based on the delete list; performing a rename operation on the copy based on the rename list; and performing a copy operation based on the copy list. In one or more embodiments, performing the delete operation, the rename operation, and the copy operation on the copy of the previous backup generates a first synthetic full backup of the source data.
