Method and apparatus for content-aware resizing of data chunks for replication

摘要

Techniques for replicating data chunks in a storage system are described herein. In one embodiment, in response to a request for replicating data chunks of a source storage system having a first average chunk size to a target storage system having a second average chunk size, a new chunk size is determined based on metadata of the data chunks in view of an average chunk size of the target storage system. The data chunks are resized based on the new chunk size to generate resized data chunks. The resized data chunks are transmitted from the source storage system to the target storage system for replication.
