IBM System Storage Archive Manager
The IBM System Storage Archive Manager feature is sold as a separately licensed software 
product that is integrated into Tivoli Storage Manager Server software. It requires a 
stand-alone Tivoli Storage Manager Extended Edition server to be dedicated for its use. It is 
accessible solely through the Tivoli Storage Manager API by various content management or 
archive software applications.

IBM System Storage Archive Manager provides support in the following key areas:
/SM590000Data retention protection (DRP): Data is not deleted until the retention criteria for the 
object is satisfied. This feature affects Content Manager OnDemand on loads, unloads, 
application group deletes, and the expiration of data.
/SM590000Event-based retention policy: Data is retained based on a time interval after the 
occurrence of a retention-initiating event. For Content Manager OnDemand, this event is a 
call to delete the data. A load, an unload, application group delete, or expiration of data 
triggers the retention event.
/SM590000Deletion hold: Data is not deleted or modified until the deletion hold is released. Content 
Manager OnDemand does not take advantage of this feature. Content Manager 
OnDemand uses its own built-in deletion hold mechanism that is called Enhanced 
Retention Management.
/SM590000New device support: Support is available for all of the devices that Tivoli Storage Manager 
Extended Edition supports.
Content Manager OnDemand operation with the Tivoli Storage Manager 
server API
With the new event-based retention policy, the object expiration can now be event-based 
instead of creation-based. A new option is available in the archive copygroup definition that is 
called RETINIT. It determines the time when the retention time that is specified by the RETVER 
attribute is initiated. Two values are possible:
/SM590000Creation: This value specifies that the retention time that is specified by the RETVER 
attribute is initiated at the time that an archive copy is stored on the Tivoli Storage 
Manager server. 
/SM590000Event: This value specifies that the retention time that is specified in the RETVER parameter 
is initiated at the time that a client application notifies the server of a retention-initiating 
event for the archive copy. If you specify RETINIT=EVENT, you cannot also specify 
RETVER=NOLIMIT.
We compare the behavior of Tivoli Storage Manager when Content Manager OnDemand data 
is deleted with the previously listed two options together with the setting of data protection.
