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:
1 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.
2 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.
Backing Up and Restoring Characteristics by Controller Models
The following table describes the backup and restore capabilities and characteristics for all wireless
controllers.

provided they end in ‘-rescueuser.tgz’
USB device
•
File name must end in ‘-
•
rescue-user.tgz’
Backing Up Image File Name
The default file name used for backup image is: <hostname/domain>-<platform>-<version>rescue-user.tgz
In order to distinguish multiple backup images, rename the file when saving to flash or FTP. If
modification is required, you should prepend the custom text to the default image name.
Backing Up the Current Image During the Upgrade Process from the Wireless Assistant GUI
You must follow the procedures detailed in this section if you want to backup the current image via the
Wireless Assistant GUI while upgrading the image. For more information on how to upgrade the image,
see Upgrading Using the GUI on page 32.
Note
When you backup the current image, the license activation key and option keys are also backed up.
External Storage
The wireless controller support only the USB storage device. If you select the Flash option to backup
the existing image, the image will be backed up on the USB device. You must ensure that the USB
device is installed and mounted on the wireless controller. For more information, see Working with an
External Storage Device on page 41.
To Back Up the Existing Software:
1 From the top menu, click Wireless Controller. The Wireless Controller Configuration screen is
displayed.
2 From the left pane, click Administration > Software Maintenance. The WLC Software tab is
displayed.
3 Select the Backup system image to: checkbox and choose the appropriate backup option.
To save the existing software image in local storage, select the Local option. The upgrade process
will delete the previous backup image stored in local storage (if one exists).
To save the existing software image on the flash device, select the Flash option, and then type a file
name for the backup image in the Filename box.
SCALANCE WLC711 Maintenance Guide 9
Backing Up and Restoring the Image
Backing Up the Current Image During Upgrade from the CLI
Note
The backup image file name is self generated when saved for both local or remote options (for
example, WLC-<platform>-09.21.01.0001-rescue-user.tgz). It is recommended that you maintain this
format for the backup image file name. If you must customize the file name, prepend the
customized file name to the original generated file name of the backup image.
To save the existing software image on a remote FTP server, select the Remote option, and then
type the following:
FTP Server – The IP address of the FTP server that stores the image file.
User ID – The user ID used to log on to the FTP server.
Password – The corresponding password for the user ID.
Confirm – The corresponding password for the user ID to confirm the password was typed
correctly.
Directory – The directory on the server in which the image file is stored.
Filename – The image file name, which must end with -rescue-user.tgz.
Backing Up the Current Image During Upgrade from the CLI
A backup image can be created during an upgrade from the CLI.
1 Check the backups present on the controller by running the show upgrade command.
WLC.siemens.com# show upgrade
1: AC-MV-09.01.01.0123-1.vps
2: vps-08.31.01.0192-rescue-user.tgz
If you want a local backup file to be created, the upgrade process will remove any previous *rescue-user.tgz file. Optionally, you can remove any existing local backup file by running the no
upgrade <filename> command.
WLC.siemens.com# no upgrade 2
The command will delete the image with index 2, which, in this example, is
vps-08.31.01.0192-rescue-user.tgz. You can also specify the full image name.
2 Upgrade the software with a backup image to local storage using the upgrade ac new-image-
name bckto local command. During the upgrade process, a backup image with the default
backup image name is created on the local storage:
upgrade ac AC-MV-09.01.01.0123-1.
vps bckto local
3 Upgrade the software with a backup image to flash using the upgrade ac new-image-name
bckto flash [filename] command.
upgrade ac AC-MV-09.01.01.0123-1.
vps bckto flash
The command will upgrade and create a backup image with the default name on the flash drive.
SCALANCE WLC711 Maintenance Guide 10
Backing Up and Restoring the Image
Backing Up the Current Image from Rescue Mode
You can also specify the custom name for the backup image.
upgrade ac AC-MV-09.01.01.0123-1.
vps bckto flash DanubeWLCvps-08.31.01.0192-rescue-user.tgz
4 If backing up the software to FTP, set up the FTP server credentials before running the upgrade by
running the upgrade_backup_dest ftp server ip user password dir file command.
upgrade_backup_dest 192.168.4.10 test abc123 system/backups
WLCvps-08.31.01.0192-rescue-user.tgz
The name specified for “upgrade_backup_dest” is used as the backup file name.
5 Start the upgrade by running the upgrade ac new-image-name bckto ftp command.
upgrade ac AC-MV-09.01.01.0123-1.
vps bckto ftp
The command first makes a backup image of the running system preserved on the FTP server, then
installs the selected upgrade image.
Backing Up the Current Image from Rescue Mode
You must follow the procedures in this section if you are backing up the current image.
You can also backup the current image via the Wireless Assistant GUI. For more information, see
Backing Up the Current Image During the Upgrade Process from the Wireless Assistant GUI on page 9.
To Back Up the Existing Current Image:
1 Connect to the console port. Do not use the ESA ports or the Admin management port. For more
information, see Using the Console Port on page 45.
2 Reboot the system.The following menu appears during the reboot process.

Restoring the Rescue Image
The rescue image resides on the wireless controller’s hard disk in a separate partition called the rescue
partition; the running software image is stored in the normal mode partition.
You can restore the rescue partition in the rare event that it becomes unavailable or corrupted (for
example, because of a hardware disk hardware error or a power failure during upgrade). To restore the
rescue partition, you must obtain a healthy rescue image and install it on the wireless controller.
A healthy rescue image is available from the following location:
The normal mode partition. A locally saved rescue image is delivered as part of the upgrade image
•
and saved on the normal mode partition during the upgrade process.
Table 3: Rescue Image File Naming Conventions
Wireless Appliance Model Rescue File Extension
WLC711 .rvps
Note
Use the restore procedure in an emergency only when the rescue partition is not accessible. Restore
commands are available in the CLI to administrators only; these commands are not listed when you
enter the help command.
SCALANCE WLC711 Maintenance Guide 21
Backing Up and Restoring the Image
Restoring to Factory Default
To Restore the Rescue Image:
1 Log into the CLI as administrator from the console or by using SSH.
2 List the locally saved rescue images by entering the command:
WLC.siemens.com# show restore-rescue
1: rescue.vps
If a rescue image exists, go to step 3; if no rescue images exist, skip to step 5.
3 To restore the rescue partition using the locally saved rescue image, enter the command: restore-
rescue local imagefilename
For example, to restore from the locally saved rescue image, rescue.rvps, enter the command:
WLC.siemens.com# restore-rescue local rescue.vps
4 To restore the rescue partition from any repository site:
a Download the appropriate rescue image to the locally accessible FTP server. Make sure that the
rescue image you download matches the main image (platform and version). Table 3: Rescue
Image File Naming Conventions on page 21 lists the platforms and the corresponding rescue
image file extensions.
b Download the rescue image from the FTP server and install it into the controller by entering the
following command:
restore-rescue ftp serveripuserpassworddirimagefilename
For example, to download the rescue image for the controller from the FTP site and, as the user
admin with the password abc123, install the rescue image, AC-MV-09.01.01.0183-1.rvps, into the
store directory, enter the following command:
WLC.siemens.com# restore-rescue ftp 1.1.1.1 admin abc123 store/ ACMV-09.01.01.0183-1.vps
Restoring to Factory Default
To restore the system to a particular image with factory defaults, restore the system from rescue mode
with the upgrade image as the restore image.
For example, if the system needs to be restored to factory default image V9.21, enter the rescue mode,
follow the procedure to restore the backup image (as explained in Restoring the Backup Image from
Rescue Mode on page 18) and, instead of selecting the backup image, provide the upgrade image V9.21
(local, flash or download from FTP), and perform the restore. The system is restored to the V9.21 with
factory default values.
Be aware that restoring a system to factory defaults means that the configuration is lost including the
IP connectivity, certificates, and licenses. Restoring to factory default is possible only from rescue
mode.
