Create a retention rule update maintenance task to globally
modify the number of report output versions, document content versions,
and report history that are currently kept in the content store.
About this task
Administrators use the retention rule update task to specify
the number of reports, queries, analyses, and document objects to
keep in the content store. You can specify how long to keep the history
and output versions in the content store. Anything that is older than
the date you specify is deleted from the content store. This update
task marks output versions to be deleted from the content store if
the output versions do not follow the defined retention rule. A background
task in content manager deletes the marked objects from the content
store. To reduce the content in the content store, consider keeping
a maximum of two versions in the content store and archiving older
versions in your external repository.Important: Run this
task only after creating and running the content archival task. If
you run it before, content that was not marked for archival is permanently
deleted from the content store.
