How SnapLock automatically commits files to WORM state

The SnapLock autocommit feature, available in Data ONTAP 7.2 and later, is an adjustable timer that commits files to the WORM state if the file does not change during a specified delay period. You can automatically commit files on a SnapLock volume to the WORM state without using any other application. This way of committing files permits existing applications to be used with SnapLock without any change.

The minimum delay that can be specified is two hours. Autocommit does not take place instantly when the delay period ends; instead, it is a minimum amount of time that will pass before the storage system queues up the service to interrogate the file system to see which files are eligible for locking. Autocommits are performed using a scanner and can take some time.

• Setting the time delay before automatically committing to the WORM state
  You can set a global option that determines how long a file must remain unchanged in the SnapLock volume before it is committed to the WORM state.
• Displaying the time delay before files are automatically committed
  You can view the time delay used to automatically commit files to WORM state. This information helps you to know the autocommit time delay, which you can change if the current delay is too short or too long.
