NOTE: Network administrators can now use the nightly backup from a 32-bit AMP to restore AMP on a 64-bit installation, rather
than having to create a special backup file or use the special restore script.

Using AirWave Failover for Backup

The failover version of AirWave provides a "many to one" hot backup server. The Failover AirWave polls the
watched AMPs to verify that each is up and running. If the watched AirWave is unreachable for the specified
number of polls, the Failover AirWave automatically restores the most recent saved backup from the watched
AirWave and begins polling its APs.

Navigation Section of AirWave Failover

The Navigation section displays tabs to all main GUI pages within AirWave Failover. The top bar is a static
navigation bar containing tabs for the main components of AirWave, while the lower bar is context-sensitive and
displays the subtabs for the highlighted tab.

Adding Watched AirWave Stations

Navigate to the Home > Watched AMPs page to begin backing up and monitoring AirWave stations. Once an
AirWave installation has been added to the Watched AMP list, the Failover AMP will download the most recent
backup and begin polling. The Failover AMP and the Watched AMP must be on the same version or else the
watched AirWave will be unable to restore properly. If any of the watched AMPs are not on the same version of
AirWave, you will need to upgrade. The Failover AMP will need HTTPS access (port 443) to the watched AMP to
verify that the web page is active and to fetch downloads.
Once the Failover AMP determines that the Watched AMP is not up (based on the user-defined missed poll
threshold) it will restore the data backup of the Watched AMP and begin monitoring the watched AMP APs and
devices. There are many variables that affect how long this will take including how long client historical data is
being retained, but for an AMP with 1,000 APs it might take up to 10 minutes. For an AMP with 2,500 APs, it
might take as long as 20 minutes. The Failover AMP will retain its original IP address.
In summary, the Failover AMP could take over for the Watched AMP in as little as five minutes; it might take up
to an additional 10-20 minutes to unpack the watched AMP data and begin monitoring APs. The most important
factors are the missed poll threshold, which is defined by the user, and the size of the watched AMP backup,
