When to Use Secondary Disk Storage

Select a destination for SYSOUT group archiving based upon retrieval frequency and retention period.

Use primary disk storage to store:

• SYSOUT groups that you must view frequently because the SYSOUT group is always available for immediate retrieval.
• Any SYSOUT group with a relatively short retention requirement because primary disk space is reusable and the space quickly becomes available again.

Use secondary disk storage (optical disk) to archive:

• Any SYSOUT group with a relatively long retention period
• Any SYSOUT that is frequently required for viewing.

When an optical disk is used for this kind of storage, it is an extremely reliable and cost effective medium.

Use tape storage to back up SYSOUT groups on primary or secondary disk.
