Here's everything that you need to know about Core Purge Service Settings.

When data is deleted from a Depot or when Templates are deleted from Management Studio, the items are marked for delete but they remain in the DataStoreDSX database until a Core Purge Service is run. The default Core Purge Process (named 24/7) runs all the time and deletes the data which is marked for delete. Core Purge processes can be created and deleted, as required.

The Core Purge Options are described in Table 31.
