Preparation
To create a backup copy of the current configuration of the controller using remote file copy servers, do
the following:
- Start the corresponding server on the PC/server in the network.
- Provide the ability to save files in the server working directory.
- Provide IP connectivity between the upgraded WLC controller and the remote file copy server
server (routing). - Ensure operation of the remote copy protocol between the WLC and the remote file copy server
server (intermediate firewalls). - If necessary (for ftp, sftp, scp, http protocols), find out the username and password to write the
required the required file.
To create a backup copy of the current configuration of the service router on a locally connected USB/MMC
storageMMC storage:
- Format USB/MMC partition as FAT32.
- Connect the USB/MMC storage to the appropriate WLC slot

Copying a configuration backup to the WLC controllers is possible both using remote file copying protocols
and protocols and to locally connected USB/MMC media.

- Start the corresponding server on the PC/server on the network.
- Place the file with the previously created backup copy of the controller in the server working directory
- Configure the controller to establish IP connectivity with the remote file copy server.
- Provide IP connectivity between the upgraded WLC controller and the remote file copy server
server (routing). - Ensure operation of the remote copy protocol between the WLC and the remote file copy server

To restore the controller configuration from a backup copy from a locally connected USB/MMC storage,
do do the following:
- Format USB/MMC partition as FAT32.
- File with a previously created backup copy of the controller configuration must be placed on the
USBthe USB/MMC media. - Connect the USB/MMC storage to the appropriate ESR slot.
