Automatic File Retention

The automatic file retention feature can be used with both mandatory and privileged file retention. When the grace period is set to a non-zero value, the file is automatically retained for the default retention period when the file has not been modified for the grace period. Until the grace period expires, the file can be modified—including its name, attributes, and ACL—or deleted. If necessary, the grace period can be modified by a user with the retentionAuto authorization.

If a filesystem is written to, the share's, project's, and pool's expiration is set to now plus the grace period plus the default retention period to protect the share, project, and storage pool. For this reason, after automatic retention is in effect, the grace period can be decreased, but not increased or unset.
