A. Attempting to restore silver_copy will fail.
B. Attempting to restore gold_copy will fail.
C. Both backups will be available for restore without question.
D. Attempting to restore gold_copy may or may not succeed.
E. You will not be able to restore either gold_copy or silver_copy

　　Since the retention policy is set to redundancy of 1,the gold_copy(obsolete) backup is not required to meet the retention criteria.Since the backup was not made in a way that will exclude or alter the retention criteria,then the gold_copy backup is no longer needed and may be removed at any time.It is possible that it will still be available for restore purposes,however.
