Novell allows users to set properties on files that are stored in a proprietary format that our clients can not recognize. Because these properties are in a proprietary format the standard unix calls to identify the properties will not work, they have to be called using Novell's proprietary format. Because of this if a user has these properties configured and our system does a backup of the files it will strip out the proprietary properties, backing them up with just the standard unix properties.

Novell has on their website a script that will record these properties into a plain text file that can be backed up along with the regular files, which can then be restored along with the files and used to restore the proprietary properties.
The script and information on how to use it can be found here:

Users should be able to have this script run before a backup to generate the files they need to generate the text files every time they run a backup.
