Step 9 - Pre-/Post Actions
Next, specify the optional pre- and post-actions. These are essentially scripts that can be executed prior to and immediately following backup. For instance, you can run a script that turns off the computer when the backup plan completes executing. Alternatively, you can run a script that, say, disables all incoming connections during the plan execution. Backup chain allows you to automatically trigger another backup plan when the current one completes.
