HP StorageWorks 8000 NAS - Manual (Page 162)

160 Integrating with Network Backup Applications
When you run a backup, data from the NAS server transfers over the network
to the backup server running the backup application, and then to the backup
server-attached tape device. The backup application cannot control a tape
library or other tape devices connected to the NAS server.
Note If the backup application is running under NT, the restore
operation recovers both the NT and UNIX security settings for
each file. If the backup application is running under UNIX, the
restored NT files revert to the default user security setting, while
UNIX files retain their full security settings.
The information covered in this section pertains only to specific tasks you must
perform to use these applications with your HP NAS 8000 device. For general
information about the backup software, refer to the user's manual that came
with the backup software.
