Administering the MARS Appliance
Where NFSSeverIP is the value specified in the Remote Host IP field and archive_path is the value
specified in the Remote Path field in the settings found in the web interface at Admin > System
Maintenance > Data Archiving. You must identify the NFS server by IP address, separated by a :/ and
then the pathname NFSSeverIP:/archive_path. For more information on these settings, see
Data Archive Setting for the MARS Appliance, page

When the restore operation completes, you may need to delete, re-enter, and re-discover all the devices
that are missing from the MARS archive file.
Upsizing a MARS Appliance
You can migrate, or upsize, to a different appliance model by following the same process and restrictions
as configuring a standby or secondary appliance. The technique involves restoring a backup from the
original, source appliance on the replacement appliance.
To restore to a different replacement appliance, you must restore to an appliance of the same model or
higher. For example, you can restore an image from a MARS 20 to a MARS 20, MARS 50, MARS 100,
or MARS 100e; however, you cannot restore a MARS 50 to a MARS 20. Restoring to a replacement
appliance differs from restoring to the actual appliance that performed the archive.
This operation cannot be used to migrate from 4.3.x to 5.3.x, as the software version on the replacement
Note
appliance must match that of the software version used to create the backup image.
The following issues must be addressed when restoring to a replacement appliance:
•
•
•
Because a single image of the complete system configuration data is archived and updated daily, no
matter what period you select from an archive, the system configuration data includes the most recent
changes. In other words, selecting a period that is 365 days old affects only the event data. The system
configuration that is restored mirrors that of the most current archive.

You must purchase a new license key for the replacement appliance. Each license key is associated
with the serial number of the appliance to which it is assigned.
You must enter that new license key on the restored image before you can log into the replacement
appliance.
When restoring the image to the replacement appliance, you need to take the source appliance off
the network or perform the operation behind a gateway that can perform NAT. When the replacement
appliance comes up and you are on the same network, you receive an IP address conflict error,
because the IP address assigned to the replacement appliance exactly matches that of the source
appliance.
