1. A system for synchronization of source and replicated instances of sequential access storage components with a backup catalog in a computing environment, comprising:

  • at least one processor device operable in the computing environment, the at least one processor in communication with a source component and a replicated component, wherein the at least one processor device is adapted for;

    subsequent to a storage operation performed on the source instance by the source component, sending a synchronization message to the replicated component for the replicated instance, wherein the synchronization message is stored locally in a persistent storage location associated with the source component along with an indicator representative of a time the storage operation was performed,pursuant to receipt of the synchronization message by the replicated component, updating the replicated component to a dirty state to indicate a lack of full synchronization between the source and replicated instances, andacknowledging receipt of the synchronization message by the replicated component to the source component by sending a dirty state acknowledgement;

    wherein if, during a subsequent recovery process, the dirty state is not yet cleared, the replicated component is deemed ineligible for participation in a full restoration operation.
