/SM590000Tape backup requested and media type: The Tape backup requested field indicates 
whether a one-time tape backup must be made of the data before it is archived. The Media 
type field indicates the type of tape to use for the backup. 
/SM590000Storage levels in this policy: This section determines the path that the archived data 
follows through the different archive storage media. The order of the levels determines the 
migration sequence. Storage levels are created by placing the cursor on an existing 
storage level (if one exists) and clicking Add Before or Add After. The Migration Policy 
Storage Level Definition window (Figure 5-22) opens.

 Important: The aggregation process occurs before the migration of the object from 
disk to the first ASM storage level. Only aggregate files that are closed are eligible for 
migration by ASM. If the specified maximum file size is large and the size of the 
archived objects is small, the aggregate file can remain open for long periods. Also, the 
Content Manager OnDemand objects might remain on disk longer than the period that 
is specified by the application group. Choosing to close the aggregate after a specified 
period addresses this problem.
