These include refreshing data in a memory and disk cache, various data synchronisations, and deleting unnecessary data and system processes.

#### Common settings for all scheduled Jobs

The basic parameter for each job is information about the frequency with which it will run.   
It is possible to set it to run every minute, or maybe just once a month.   
The syntax known as [CRON](https://en.wikipedia.org/wiki/Cron) is used for this and there are always five items in the configurator (Minute, Hour, Day of the Month, Month and Day of the week).
