Backing Up the Primary GSSM
This section describes the procedure to perform a full backup of the primary
GSSM database. It contains the following sections:
• Backup Overview
• Performing a Full Primary GSSM Backup
Backup Overview
The GSSM database of the primary GSSM is the heart of your GSS network. 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.
Because the primary GSSM database is so important to the continued operation
of your GSS network, it is important that you make frequent backups of your
primary GSSM and its database. Frequent backups ensure that if a sudden and
unexpected power loss or media failure occurs, your GSSM configuration and
database survive, and your GSSM can be quickly restored to operation.
Perform a backup of your primary GSSM:
• Before switching GSSM roles and before making the standby GSSM your
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
During the backup process, 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 provides you with the flexibility to pick and choose the specific GSSM
configuration information you wish 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.
