Abstract
Systems, methods, and computer readable storage mediums for maintaining the history of remapped data in a storage system. A first portion of a first medium may be remapped to a second medium as part of read optimization operations, wherein the second medium is younger than the first medium. A tag associated with the first portion of the first medium may be retained when the first portion is remapped to the second medium. When the second medium is replicated to another storage array, the first portion of the first medium may be prevented from being replicated based on the tag identifying the first portion as being part of a previous replication operation.
