Issue



Backup of NSS volumes on SuSe OES 2servers using Backup Exec 2010 with RALUS, are successful, but restore of some folders or directories are missing some extended attributes and trustees.


Environment



SuSe OES 2 sp1, being backed up by Backup Exec 2010 with RALUS (Remote Agent for Linux/Unix Servers)


Cause



SMS is generally used when doing backups to preserve extended attributes such as trustees, file/directory ownership, etc. In Netware, SMS was required to preserve this information when backing up NSS and traditional volumes. Netware metadata, is not fully available to Backup Exec, due to missing parameter in OES configuration.

Solution



These parameters can be added to the /etc/opt/novell/nss/nssstart.cfg file. Make sure there are no typos or this could cause nss to fail to load. In the nssstart.cfg file the parameters would be set thus:
 
/ListXattrNWMetadata 
/CtimeIsMetadataModTime
 
The ListXattrNWMetadata exposes an extended file attribute called  "netware.metadata".   Backup Exec is then able to fully backup and restore the file system and all the extended attributes and trustee information.
