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 performing accelerated and memory efficient similarity matching. A data stream having a plurality of data zones is received. Each zone includes a zone identifier. A plurality of hashing values for each zone are generated. Each hashing value is generated based on a portion of a zone. A storage structure having a plurality of storage containers is generated. Each storage container stores one or more hashing values associated with each respective storage container and a plurality of zone identifiers referencing the associated hashing values. At least one storage container includes a listing of zone identifiers stored in each storage container. Using the storage structure, the received data stream is deduplicated.

Accelerated and memory efficient similarity matching

A method, a system and a computer program product for performing deduplicating data. A data stream having a plurality of data zones is received. One or more data storage locations in a plurality of data storage locations for deduplicating one or more zones in the plurality of zones is identified. Each data storage location stores its respective deduplicated data zones. A data storage location for deduplicating a first data zone is selected. The first data zone is deduplicated using the selected data storage location.

Similarity matching

A system, a method, and a computer program product for or managing grid server system resource(s) are disclosed. A processor of a grid server in a plurality of grid servers determines an ingestion rate of data received by the grid server for a backup. The ingestion rate corresponds to a speed of transferring of the received data into a memory of the grid server. The processor determines a deduplication and replication rate of the received data. Deduplication represents a deduplication of the received data by the grid server. Replication represents replication of the deduplicated received data to another server in the plurality of servers. The processor adjusts the deduplication and replication rate based on the ingestion rate.
