This option determines whether or not the backup job completes before the resynchronize operation has finished (default is No). Yes means that a resynchronize request is issued, but the backup does not wait for the resync operation to complete. No means that the backup job cannot reach completion until the resynchronize operation has finished.

Choosing Yes may allow more efficient use of backup resources. If two backups need the same tape drive, the second can start even though the resynchronize operation for the first job has not completed.
