Chapter 1 Maintaining Your WAAS System
Backing Up and Restoring your WAAS System
Note The backup and restore methods described in this section apply only to a WAE device that is not
configured as a WAAS Central Manager. For information on backing up the WAAS Central Manager
device, see the “Backing Up and Restoring the WAAS Central Manager Database” section on page 1-9.
You can use either of the following methods to back up and restore the database of an individual WAE
device:
• WAE Device Manager—For information on using the WAE Device Manager to back up and restore
a device’s database, see the “Backing Up the Configuration Files” section on page 1-6.
• CLI—You can use the copy running-config command to back up and restore a device’s
configuration. This command saves the currently running configuration.
Additionally, you can restore a WAE to the default configuration that it was manufactured with at any
time by removing the user data from the disk and Flash memory, and erasing all existing files cached on
the appliance. Basic configuration information, such as network settings, can be preserved. The
appliance is accessible through Telnet and Secure Shell (SSH) after it reboots.
Note If software upgrades have been applied, the restoration process returns to the defaults of the currently
installed version and not the factory defaults.
To restore a WAE to its factory defaults or the defaults of the current configuration from the CLI, use the
restore factory-default [preserve basic-config] EXEC command.
For more information about the CLI commands, see the Cisco Wide Area Application Services Command
Reference.
Reinstalling the System Software
This section contains instructions for using the software recovery files to reinstall your system software
if for some reason the software that is installed has failed. A software
recovery CD-ROM ships with
some WAE and WAVE hardware devices and some WAVE devices use a USB flash drive for recovery.
Caution If you upgraded your software after you received your software recovery CD-ROM or image files, using
the recovery software images may downgrade your system. Ensure that you are using the desired
software recovery version.
The WAAS software consists of three basic components:
• Disk-based software
• Flash-based software
• Hardware platform cookie (stored in flash memory)
All of these components must be correctly installed for WAAS software to work properly.
The software is contained in two types of software images provided by Cisco Systems:
• A .bin image that contains disk and flash memory components (the Universal version of the WAAS
software)
• A .sysimg image that contains a flash memory component only
