Backing Up Configuration Files

All switch configurations reside in the internal system: and nvram: file systems. If your internal file
systems are corrupted, you could potentially lose your configuration. Save and back up your
configuration files periodically. Also, before installing or migrating to a new software configuration,
back up the configuration files.
