 ## Cron jobs
 
 To execute [background tasks](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/background_jobs_configuration.html) by using system cron instead of default Ajax cron, set `cronjob.enabled` parameter to `true`. Background jobs are important for tasks that do not necessarily need user intervention, but still need to be executed frequently (cleaning up, sending some notifications, pulling RSS feeds, etc.).
