Systems and methods for replication time estimation in a data deduplication system

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

• determining maximum streams based on a number of allocated streams on a source node and a number of allocated streams on a target node;
• determining an available network bandwidth between the source node and the target node;
• estimating a delta time based at least on one or more duplicate fingerprints between a logical space unit of the source node and the target node by using at least one source smart filter and at least one target smart filter;
• and
• determining a replication time based on the maximum streams, the available network bandwidth between the source and target nodes, the estimated delta time, and a number of unique fingerprints that exist between the logical space unit of the source node and the target node.

A data processing system, comprising:

• a processor;
• and
• a memory coupled to the processor to store instructions, which when executed by the processor, cause the processor to perform operations, the operations including:
• determining maximum streams based on a number of allocated streams on a source node and a number of allocated streams on a target node;
• determining an available network bandwidth between the source node and the target node;
• estimating a delta time based at least on one or more duplicate fingerprints between a logical space unit of the source node and the target node by using at least one source smart filter and at least one target smart filter;
• and
• determining a replication time based on the maximum streams, the available network bandwidth between the source and target nodes, the estimated delta time, and a number of unique fingerprints that exist between the logical space unit of the source node and the target node.
