Creating a Backup Image

When creating the image backup, the wireless controller makes an exact copy (snapshot) of the running image and saves it as a tgz file. Restoring the controller with a backup image restores the appliance to the exact state at the time backup was created.

A backup image can be created in two ways:

During upgrade of the image. Before installing the new image version, the upgrade process takes the backup of the running image. The backup image can be stored locally, on a flash drive (if present), or remotely on an FTP server.
From rescue mode using the menu driven commands. To do this, you have to enter rescue mode on startup. No service to clients is provided while you are in rescue mode. Again, the backup image can be stored on the local, flash (if flash is present) or an FTP server.

The only way to create a backup image independently of an upgrade is to run it from the rescue mode.
