The enablearchiveretentionprotection option specifies whether to enable data retention protection for archive objects on a Tivoli Storage Manager server that is dedicated for this purpose. Your Tivoli Storage Manager server administrator must activate data retention protection on a new Tivoli Storage Manager server that does not already have stored objects (backup, archive, or space-managed). If the API application attempts to store a backup version or space-managed object on the server, an error message is issued.
The note in Considerations for designing an application states: "Do not store objectID values to use for future restores. They are not guaranteed to be persistent during the life of the object." can be relaxed for Archive manager applications since the archive-manager server does not support export or import. Archive-manager applications can save and use the objectID to improve the performance during object restore.
If the Tivoli® Storage Manager server issues the SET ARCHIVERETENTIONPROTECTION ON command, you cannot delete an archived object from the server by using the delete filespace command, until the policy parameters of the archive copy group are satisfied. See the appropriate Tivoli Storage Manager server Administrator's Reference for information about how to set up a management class.
