Answer

Available methods to back up ONTAP configuration settings:

  • System configuration backup 
    • Use the system configuration backup create -node <node-name> -backup-name <name> command.
    • Backs up cluster and node configuration data.
  • AutoSupport 
    • When enabled, AutoSupport regularly collects and sends system configuration information.
    • Extract configuration files (such as /etc/rc, /etc/hosts, /etc/fstab, /etc/exports, /etc/group, /etc/passwd) from AutoSupport packages for backup or review.
  • Manual command output 
    • Output key configuration details to text files using ONTAP CLI commands.
    • Example commands: 
      • cluster show
      • vserver show
      • network interface show
      • volume show
      • export-policy rule show
    • Save command outputs before and after upgrade for comparison.
  • Note:
    • System configuration backup is primarily for restoring configuration on the same ONTAP version. 
    • Restoring configuration backups across different ONTAP versions is not supported.

Additional Information

Comparing configuration differences before and after upgrade:

  • Save system configuration backup files and CLI command outputs before and after the ONTAP upgrade.
  • Use a file comparison tool (such as WinMerge or the diff command) to compare text outputs and identify differences.

Note: System configuration backup files are in binary format. Extract contents for comparison if needed.

  • AutoSupport content can be exported as text and compared similarly.
