In Version 9.7 Fix Pack 3 and later
fix packs, you can use new backup parameters to specify that the target
storage device supports data deduplication. These new parameters optimize
the format of backup images for deduplication devices and make backup
operations more efficient.
You can use the DEDUP_DEVICE parameter of
the BACKUP DATABASE command or set the iOptions parameter
of the DB2Backup API to DB2BACKUP_DEDUP_DEVICE.
In Version 9.7 Fix Pack 4 and later fix
packs, this feature is also integrated in the ADMIN_CMD procedure.
