GSSM database. It contains the following topics:

Backup Overview
The GSSM database maintains all network and device configuration information,
as well the DNS rules used by the GSS devices to route DNS queries from users
to available hosts.
Note
You should perform frequent backups of your primary GSSM and its database to
ensure that if a sudden and unexpected power loss or media failure occurs, your
GSSM configuration and database will survive, and your GSSM can be quickly
restored.
We recommend that you perform a backup of your primary GSSM:
•
Before you switch GSSM roles and before you make the standby GSSM the
primary GSSM on your network
•
Before you perform a GSS software upgrade
•
After you make any changes in the device or network configuration of your
GSSM
The GSS software performs a full backup of the GSSM network configuration
settings as well as the GSSM database that contains global server load-balancing
configuration information. A full backup of the primary GSSM allows you to pick
and choose the specific GSSM configuration information that you want to later
restore on the primary GSSM.
Whenever you execute a backup on your primary GSSM, the GSS software
automatically creates a tar archive (“tarball”) of the necessary files. A tar archive
is a group of files collected together as a single file. This file has the .full
extension.
