Configuring and Performing Appliance Data Backups
•
•
During a typical restore process, the MARS Appliance is first re-imaged from the DVD, upgraded to the
correct version of software, and then the restore operation is performed. During the DVD re-image
process, the name of the appliance is changed to the factory default, which is pnmars. If you do not wish
to change the name of the appliance before you attempt to restore it from the NFS server, you must ensure
add an entry for pnmars to the DNS server or in the /etc/hosts file on the NFS server so that during the
restore operation, the NFS server can perform an IP address-to-hostname lookup for the MARS
Appliance.
After the restore operation completes, the MARS Appliance will be restored to the name saved in the
archived OS package. You should have included this name already in the DNS server or /etc/host file of
the NFS server. Otherwise, this archive/restore operations may not function properly.
Configure the Data Archive Setting for the MARS Appliance
You can archive the data and the system software that is running on a MARS Appliance to a remote
server. This data archival includes operating system (OS) and upgrade/patch data, system configuration
settings, and dynamic data, such as system logs, incidents, generated reports, and the audit events
received by the appliance. The feature provides a snapshot image of the appliance.
While complete system configuration data is archived, the dynamic data that is archived includes only
Note
the data that is received or generated after you enable the data archive setting. Therefore, we recommend
that you enable archiving before configuring your appliance to receive audit events from reporting
devices.
Using archived data, you can restore your appliance in the event of a failure, as long as the data is not
corrupted. In this capacity, data archiving provides an alternative to re-imaging your appliance with the
Recovery DVD.
Before You Begin
You must set up the NFS server correctly to archive the appliance's data. See
on Windows, page 6-24
You must configure the basic network settings for the appliance.
To configure the data archive settings for a given MARS Appliance, follow these steps:
Select Admin > System Maintenance > Data Archiving.

Add the NFS client (MARS Appliance) info in /etc/hosts file on the NFS server. The hosts file is
located at WINDOWS\system32\drivers\etc\ on Windows servers.
Add the MARS Appliance information to your DNS server.
