In OES SP2 and later, NSS provides an extended attributes (XAttr) extension that supports listing, saving, and restoring the trustee information that is stored in the netware.metadata extended attribute. Third-party backup software that supports the standard Linux Extended Attributes (XAttr) can take advantage of this feature for NSS volumes to preserve trustees, trustee rights, file attributes, and quotas in backup and restore. For information, see Section 23.22, Extended Attributes Commands (Linux).
