Base system table archiving rules ensure that DevOps data stored in the Configuration Management Database (CMDB) are systematically archived and purged.

Archiving rules for DevOps data in CMDB tables

Data archiving involves managing table size growth and archiving old data. It moves data that is no longer needed every day from primary tables to a set of archive tables. For more information, see Data archiving. Base-system archive rules are configured to auto-archive DevOps tables that are older than a specified period. An archive table is created for any table that has an archive rule associated with it. You can also choose to restore data from archive tables.
Note: While you can restore any record from the archive tables. Once archived data is restored, the same data is no longer auto-archived. For more information, see Managing archived data.
  • Navigate to System Archiving > Archive Rules and select the individual archive rule whose data you restored.
  • Enable the Auto rearchive check box, to resume auto-archiving for that archive rule.

Modify base system value for archive rules

You can configure the auto archive duration for all the archive rules that are applicable to DevOps tables from the Auto archive (in months) DevOps system property. By default, this property's value is set to 9 (months). Navigate to DevOps > Administration > Properties > Auto archive (in months), to modify the value. For more information on configuring data archiving, see Create an archive rule

The following list indicates the tables that are auto-archived.

The data archiving rules feature considers and honors parent rules before individual archive rules are run. If you have an associated parent archive rule, the child rules are run only when the parent rules are run. Similarly, when you modify individual rules, you must first disable or disassociate the parent archive rule, make the configuration changes, and re-enable the parent archive rule. Changes to the Auto archive (in months) DevOps property overrides any configuration changes made to the duration of child archive rules. For example, you could update the archive rule condition for any of the Active DevOps archive rules to a custom value, say three months instead of the default 9 months. However, if you modify the Auto archive (in months) DevOps property, all modifications made to the conditions of individual archive rules are overwritten by the value in the Auto archive (in months) system property.
Note: The override function is binding for all scenarios except:
  • When an archive rule does not belong to the DevOps scope.
  • When an archive rule belongs to the DevOps scope but is inactive.

Base system destroy rules for DevOps data

Base-system destroy rules are also enabled and activated on all the archived DevOps tables. By default, data is deleted from an archived table after 36 months or 1095 days have passed from the time the data is stored in the archive table. For more information, see Create a destroy rule.
