More Information
Summary:Various embodiments for synchronization of source and replicated instances of sequential access storage components in a computing environment by a processor device are provided. A replication synchronization table (RST) is configured for the source instance. The RST is adapted for recording compacted information for at least one of a truncate and an erase operation applied on the source instance. The RST of the source instance is updated at a source component with the compacted information. The updated RST is transmitted from the source instance to the replicated instance. Based on the RST of the source instance and the RST of the replicated instance, data representative of a most recent position on the source component from which data should be transmitted to a replicated component to achieve a full synchronization is determined.
