Backup and Restore Firewall Config using ASDM

Overview

This process outlines how to backup and restore a configuration by executing line by line changes, while using a graphical user interface.

The backup files are stored on a local system as a ZIP file.

NOTE: It is important to store this ZIP file in an easily accessible place in case of an emergency. Plan a backup to be taken anytime changes are made to the firewall configuration.

If the firewall configuration is in an high-availability (HA) Pair, then ensure that the backup and restore to the Active firewall is enabled. This can verified on the Cisco Adaptive Security Device Manager (ASDM) Dashboard, under the Failover Status field. Look for Primary (Active). If this is not enabled, then login to the other firewall to perform these steps.
