    Checkpoint is a processes within SQL that writes all dirty data pages to disk. It's an automatic process.

    Checkpoints flush dirty data and log pages from the buffer cache of the current database, minimizing the number of modifications that have to be rolled forward during a recovery.

    It happens during any of the following scenario,

    1. If the database settings are altered using Alter database command

    2. When checkpoint statement is executed

    3. When Sql Server is stopped using Shutdown command or using service control manager

    Read through this link for more information about checkpoints in Sql Server,
