摘要
A method and system enable tape back-up of objects stored to an object storage platform and also enable efficient backup to a secondary storage device data objects. An offline-replica bit within a metadata of an object being stored is set to a first value, indicating that the stored object is available for secondary storage to a second storage device. In response to receiving a request for backup of one or more objects from the object storage platform: the storage controller: identifies which objects have an offline-replica bit value that is the first value; and provides only those objects requested that have their offline-replica bit value equal to the first value. An external backup tracking mechanism identifies which objects have been backed-up to the secondary storage, and only those objects that have not previously been backed up are backed up during a subsequent backup request.
