If your current configuration becomes unusable, you can replace it with the backup version. • Save your backup configuration to a remote system. • Always back up your configuration before you do a manual upgrade. If you have auto upgrades configured, make sure you do periodic backups. • Create a service account. A service account is needed for special debug situations directed by TAC. Caution You should carefully consider whether you want to create a service account. The service account provides shell access to the system, which makes the system vulnerable. Analyze your situation to decide if you want a service account existing on the system.
