Synchronization of sequential access storage components with backup catalog

Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance. 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, the replicated component is updated to a dirty state to indicate a lack of full synchronization between the source and replicated instances. Receipt of the synchronization message is acknowledged by the replicated component by sending a dirty state acknowledgement. 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.
