A method, a system, and a computer program product for protection and recovery of backup storage systems from ransomware attacks. A request to modify data stored in a storage system is received. The storage system includes at least one component configured to store the deduplicated data. An acknowledgement of the received request is generated. The acknowledgement indicates that the data stored in the at least one component and identified in the received request was modified. Modification of the data stored in the at least one component and identified in the received request for a predetermined period of time is prevented.

Protection and recovery of backup storage systems from ransomware attacks

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.

Synthetic full backups and deduplication backup storage with landing zone

A method, a system, and a computer program product for performing a backup of data are disclosed. A grid server in a plurality of grid servers is selected for deduplicating a segment of data in a plurality of segments of data contained within a data stream. The segment of data is forwarded to the selected grid server for deduplication. A zone contained within the forwarded segment of data is deduplicated using the selected server. The deduplication is performed based on a listing of a plurality of zone stamps. Each zone stamp in the plurality of zone stamps represents a zone in a plurality of zones deduplicated by at least one server in the plurality of grid servers.
