3. Manual – Like any other SQL Command, as soon as you issue the checkpoint command, it will run to its completion. This checkpoint is valid for the current database only.

4. Internal – This is not possible controlling the internal checkpoints for users. It happens when shutdowns are not clear and the recovery model is not certain. It takes place when starting the backup of a database.
