SYNTHETIC FULL BACKUPS AND DEDUPLICATION BACKUP STORAGE WITH LANDING ZONE

A method, a system, and a computer program product for executing synthetic backup processes and deduplication backup storage with landing zone. A synthetic backup of a data file is received. A partial re-synthesis of the synthetic backup of the data file is performed. A total size of the partial re-synthesized backup of the data file and the received synthetic backup is determined. A size of a complete re-synthesis of the synthetic backup of the data file is computed. The complete re-synthesis of the synthetic backup of the data file is performed when the determined total size exceeds the computed size of the complete re-synthesis of the synthetic backup of the data file.
