What to Do Next
Proceed to the
“Saving Backup Copies of Your New System Image and Configuration” section on
Saving Backup Copies of Your New System Image and Configuration
To aid file recovery and to minimize downtime in the event of file corruption, we recommend that you
save backup copies of the startup configuration file and the Cisco IOS software system image file on a
server.
Tip
Do not erase any existing backup copies of your configuration and system image that you saved before
upgrading your system image. If you encounter serious problems using your new system image or
startup configuration, you can quickly revert to the previous working configuration and system image,
if necessary.
For more detailed information, see the “Managing Configuration Files” chapter and the “Loading and
Maintaining System Images” chapter of the
Cisco IOS Configuration Fundamentals and Network
Management Configuration Guide
.
To save backup copies of the startup configuration file and the system image file, complete the following
steps.
