A storage system performs data replication with a recovery point objective (RPO). The storage system replicates data at intervals through data transfers over a network. The storage system determines bandwidth of the network. The storage system determines the intervals for replicating the data, based on size of data transfers, network bandwidth, and the recovery point objective.

Intervals for data replication

A method of replication in a distributed storage system, performed by the distributed storage system is provided. The method includes managing a first index for data or metadata in a first storage system, the first storage system having a first partitioning scheme. The method includes managing a second index for data or metadata in a second storage system, the second storage system having a second partitioning scheme. The method includes replicating the data or metadata from the first storage system to the second storage system, translating an identifier of the data or metadata from the first storage system, and mapping the replicated data or metadata into the second partitioning scheme, via the translating of the identifier of the data or metadata from the first storage system.
