archive copygroup will determine how long the objects will exist before expiring.
There are also specific backup retention and version requirements for specific
data protection modules.
Table 21-1 summarizes the backup and archive copygroup requirements for each
data protection module.

When selecting the retonly value for log backups,
ensure that it is at least as long as the value for the
backup objects the logs are associated with.
Data objects
have the same version limits and retention values. You
may want to consider storing meta objects in a
disk-storage pool so that media mount is not
necessary when doing data protection for SQL
queries. Alternatively, you can use the same
management class if you rarely need the meta objects.
Data Protection Since backup objects inserted into the Tivoli Storage
for Oracle Manager backup storage pool have unique file names,
they never expire on the Tivoli Storage Manager
server. The following options must be set to handle this
