referencingBackups property
The names of the destination backups being created by copying this source backup.
The backup names are of the form projects//instances//backups/.
Referencing backups may exist in different instances. The existence of any
referencing backup prevents the backup from being deleted. When the copy
operation is done (either successfully completed or cancelled or the
destination backup is deleted), the reference to the backup is removed.
Output only.
