Synchronization of sequential access storage components with backup catalog

A computer program product for synchronization of source and replicated instances of sequential access storage components with a backup catalog in a computing environment by a processor device, the computer program product comprising a computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• a first executable portion for, subsequent to a storage operation performed on the source instance by a source component, sending a synchronization message to a 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;
• a second executable portion for, 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;
• and
• a third executable portion for acknowledging 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.
