• RevisionCleanupScheduler - Run the RepositoryManagementMBean.startRevisionGC() method to perform a Garbage Collection of the Revision Store
• VersionCleanup - Job to traverse the JCR Version Store and remove versions (oldest-first) exceeding a configurable limit

As well as a Health Check to ensure the jobs are scheduled and have not failed.
