US 2021/0243255 A1 · EFFICIENT REPLICATION OF A DATASET TO THE CLOUD

Abstract

Synchronizing snapshots between storage systems, including: receiving, from a source storage system, an identification of a snapshot to be replicated to a destination storage system, wherein the source storage system and the destination storage system are of different types; identifying, from hint information stored on the destination storage system, a most recent version of the snapshot that is stored on the destination storage system; issuing, to the source storage system, a request for an identification of the differences between the snapshot to be replicated to the destination storage system and the most recent version of the snapshot that is stored on the destination storage system; receiving, from the source storage system, the identification of the differences; and issuing a request to transfer, from the source storage system to the destination storage system, data associated with the differences.

Claims20

Dependent claims

A method comprising:

determining the differences between a dataset to be replicated to a target storage system and a version of the dataset that is stored on a source storage system;
and
directing the target storage system to store, as part of a new version of the dataset that is stored on the target storage system, the differences between the dataset to be replicated and the version of the dataset that is stored on the target storage system, wherein the new version of the dataset does not comprise at least a portion of the dataset that is stored on the destination storage system.

An apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

determining for a dataset to be replicated to a target storage system, a version of the dataset that is stored on the target storage system;
determining the differences between the dataset to be replicated to the target storage system and the version of the dataset that is stored on the target storage system;
and
directing the target storage system to store as a new version of the dataset on the target storage system, the differences between the dataset to be replicated and the version of the dataset that is stored on the target storage system, wherein the new version of the dataset does not comprise at least a portion of the data stored in the version of the dataset that is stored on the destination storage system.
