[Option] /CheckP[ointing]{on\off} [Description] 
(Optional). Sets a value that determines whether the package will use checkpoints during package execution. The value on specifies that a failed package is to be rerun. When the failed package is rerun, the run-time engine uses the checkpoint file to restart the package from the point of failure. The default value is on if the option is declared without a value. Package execution will fail if the value is set to on and the checkpoint file cannot be found. If this option is not specified, the value set in the package is retained. For more information, see Restarting Failed Packages by Using Checkpoints. The /CheckPointing on option of dtexec is equivalent to setting the SaveCheckpoints property of the package to True, and the CheckpointUsage property to Always.
