Abstract
In general, embodiments relate to a method for generating synthetic full backups, the method comprising: performing a verification that a previous backup of source data stored in a data domain is a failed synthetic full backup, obtaining based on the verification a latest snapshot of the source data, obtaining based on the verification a prior snapshot of the source data making a determination, using a copy list that a first portion of the data items in the copy list exists in the previous backup and a second portion of the data items does not exist in the previous backup, and performing based on the determination a copy operation to copy the second portion of the data items to the data domain to obtain a synthetic full backup.
