DLO now protects all of the alternate streams for a file, including security streams. If a new version of a file contains only changes to alternate stream data, the file replaces the previous version and does not affect the revision count. Only revisions with actual data changes are treated as new revisions.
When a file is restored, one of the options is to preserve the security attributes on restored files. If this option is not checked, the security attributes are removed from the restored file. This option is set in the restore dialog box.
