The basic tasks provided by the TYPO3 Core

The Scheduler comes by default with several tasks:

Caching framework garbage collection : some cache backends do not have an automatic garbage collection process. For these it is useful to run this Scheduler task to regularly free some space.
Fileadmin garbage collection : empties _recycler_ folders in the fileadmin.
Table garbage collection : cleans up old records from any table in the database. See related section below for more information on configuration.

Most TYPO3 console command can also be executed via scheduler.

The following tasks provide configuration options that need dedicated chapters:

Providing custom tasks from your extension

More tasks are provided by system extensions, such as the Extension Manager, which defines one for updating the available extensions list.

The base tasks are also there to serve as examples for task developers (see Scheduler task development).
