# SANbox2 Configuration Backup and Restore

Configuration Backup

Changes made to the switch since it was manufactured can be saved to a file in non-volatile memory. However, the backup is lost if the switch is reset. Use the FTP User Images procedures to save the configdata file to the workstation. (In FTP, no directory listing is available. The configuration backup file is always named configdata.)

Configuration Restore

Switch configurations can be "cloned" to easily propagate an identical configuration to other switches. Use the FTP User Images procedures with the Put command to send the previously saved (using config backup) configdata file to the switch. In a Telnet session, use the Config Restore command to return the switch configuration to the previously saved configuration. The switch is automatically reset upon a successful restore.

Reinitializing the Configuration File System

If the Heartbeat LED is the 4-blink pattern, the configuration file system may be corrupted. To recover the previous switch configuration, use the Config Restore in the Telnet command line interface. The Heartbeat LED 4-blink pattern continues until a previous switch configuration is successfully restored.
