Hi,
"Single Object per Store Media" is a property of a Data Protector StoreOnce device which can be enabled in the Settings tab. If not set and a session is serially backing up objects (that is when there are more objects than available data streams to the store, limited by "load balancing MAX value" and "Max. number of Connections per Store" and Max. Number of Parallel Streams per Client System") then multiple objects will arrive onto the same store item and DP medium. This may not be desired and can be prevented by setting "Single Object per Store Media" in the following cases:
- Protection time is not equal across objects
- Object operations will use the media as a source
- Customer just finds it nicer to have the one-to-one relationship between media and object version
However, when the backup session includes a large number of very small objects the the usage of this option is not recommended as it will create many store items / DP media which may decrease performance or even introduce other issues.
