Creating a data set archive policy

You can define policies for data set archiving (migrating data sets from disk in order to free disk space).

Before you begin

Follow the steps outlined in Creating a new policy.

For a description of the following options, see Policy options:

Option	Description
Primary days non-usage	This option is not available if you check Use SMS policy. When it is available, it applies to all data sets, overwriting SMS attributes of SMS-managed data sets.
Allow archive only if backup exists	Check this option (default) to ensure that only data sets with a current backup copy will be archived. The data set will not be archived if: The data set’s change bit is on, meaning it has changed since the last backup. The data set’s change bit is off, but there is no backup copy in the system. The policy will archive the data set only if the change bit is off, and there is a valid backup copy. The policy does not check whether the backup copy is the most current one, and there is no protection from manually deleting a backup of an archived data set.
Override retention	Allows overriding the retention period that will be set for all archives done by this policy. The following override retention options are available: Forever—Archives created by the policy will be created as PERM archives with no expiration date. Period—Archives created by the policy will be created with a retention period calculated from the policy's run date Available options are DAYS, WEEKS, MONTHS, or YEARS. Date—Archives created by the policy will be created with an explicit expiration date. Once the specified date is passed, the policy will no longer be able run.

For a description of how to use the Filters tab to select resources for processing, see Filters.

During an activity run, the policy uses the defined filters and policy options to select resources, excluding the following:

Non-SMS managed data sets with unmovable or absolute DSORG
Non-SMS managed multi-volume data sets
Catalogs
Temporary data sets
Data sets using symbols to specify a VOLSER (Indirect Volume Serial Support)
All uncataloged data sets including VTOC Indexes
SYS1.** data sets including VVDSs
Generation Data Sets that are either without a catalog entry, non-SMS managed, non-active, or whose GDG base is defined with NOSCRATCH
ALIASes

The catalog entry of the archived data set is not SMS-managed.
