1. A method comprising:
generating an update set, wherein
the update set is generated by a source data mover at a source site,
the update set comprises one or more replication updates, and
the update set comprises data of the one or more replication updates and associated metadata of the one or more replication updates;
generating a restore identifier at the source site, wherein
the restore identifier facilitates resynchronization of data stored at the source site with data stored at a target site, in event of a restoration operation, by facilitating identification of that portion of the data stored at the target site that has changed since a beginning of a data synchronization interval associated with the restore identifier, using a data structure for synchronization;
sending the update set and the restore identifier to a target data mover at the target site, wherein
the sending is performed by the source data mover; and
storing the restore identifier.
