Yes, you can use Storage Lifecycle Policy to config the backup to OST STU and duplication to tape.

OST support is documented in this TN: http://www.symantec.com/docs/TECH72198

Also see SLP Best Practice guide: http://www.symantec.com/docs/TECH153154

(The reference to tape or VTL will apply to your duplicate copy)

Considerations when using SLPs with Catalog Backups
NetBackup 6.5.4 introduced the ability to use SLPs with catalog backups, however the following points need to be considered when doing this:
When writing to tape or VTL catalog backups must be directed to volume pools which have the ‗catalog backup‘ attribute set. This attribute is not checked when an SLP is configured for use with a catalog backup policy so you must check the pool attributes are set correctly when you create the storage destinations in the SLP.
If catalog backups are duplicated using SLPs additional steps are required to restore the catalog from a non-primary copy of the catalog backup. More information about this can be found in the NetBackup Troubleshooting Guide and also in TECH125748.
If catalog backups are duplicated using SLPs both parts of the catalog backup must be duplicated in the same duplication job.
Additional steps are required when recovering catalog backups from disk storage types supported with SLPs. More information about this process can be found in TECH72198

Thanks for your reply!

May I know is there anything specical for configurating catalog backup to OST? as when using physical tape, we need to use a catalog media pool.

It will be good if there is any established procedure.


Thanks

To configure Catalog backup to OST is the same as selecting a disk storage unit in the backup policy - you can choose your OST storage unit. The basic steps are documented in Admin Guide I under the topic 'Configuring a catalog backup manually'.
Please take note of the recommendation in TECH72198 to choose a media server STU.

If you want to duplicate to tape, configure SLP (howto is described in chapter 14 of Admin Guide I). The only 'special' step here is to select CatalogBackup pool for the duplication.

To recover from the duplicate copy is described in http://www.symantec.com/docs/TECH125784 .
