What Items Are Not Saved During a Configuration Backup and Restore

Items That Are Excluded During a Configuration Backup and Restore of a Cisco ASA Firewall

Configuring a Cisco ASA firewall is a meticulous task, involving a multitude of settings and parameters. As network administrators, we breathe a sigh of relief when we perform backups, knowing that our configurations are safe. But here lies the challenge – what if the backup doesn’t cover everything? What if some critical elements are left out?

And unfortunately, some things do get excluded. In a nutshell, during a configuration backup and restore of a Cisco ASA firewall, the following items are not saved:

  • 1. Dynamic Routing Protocols

Dynamic routing protocols, such as OSPF and EIGRP, are not part of the backup. These settings must be reconfigured manually post-restore.

  • 2. VPN Session Information

VPN session data, including active connections, is not saved. This means that after a restore, VPN users will need to re-establish their connections.

  • 3. Licensing Information

Licensing details, like activation keys and expiry dates, are not included. You’ll need to re-enter this information.

  • 4. Certificates and Keys

SSL certificates and cryptographic keys are not part of the backup. Make sure to store these separately.

  • 5. Captured Packets 

Packet capture data is not saved. If you rely on these captures for troubleshooting, make sure to export and save them before the backup.

  • 6. Custom Scripts and User Data 

Any custom scripts or user-specific data are not covered. Keep separate backups for these items.

  • 7. Syslog and SNMP Configuration 

Syslog and SNMP settings are not saved during backup and restore. Reconfigure them post-restore to maintain network monitoring.

Now that we’ve highlighted what’s excluded, it’s crucial to prepare for these gaps to ensure a smooth recovery process.

Are Those Items Matter? 

Knowing what’s not saved during a backup and restore operation is essential for disaster recovery planning. Neglecting these crucial elements could lead to network downtime and security risks. By understanding these limitations, you can proactively mitigate potential issues and streamline your network management.
