Backing Up AirWave

AirWave creates nightly archives of all relational data, statistical data, and log files. This occurs by default at 4:15 AM,

but is configurable on the AMP Setup > General page under Nightly Maintenance Time.

Although AirWave only keeps the last four sets of archives, the archives can be downloaded manually or automatically

off-site for more extensive backup strategies. AirWave creates one data backup file each night. The data backup file

contains all of the device and group information as well as historical data and system files, including IP address, NTP

information, mail relay hosts, and other AirWave settings.

Viewing and Downloading Backups

To view current AirWave backup files, go to the System > Backups page. Figure 135 illustrates this page.

Figure 135:System > Backups Page Illustration

To download a backup file, select the filename URL and the File Download popup page appears.

Regularly save the data backup file to another machine or media. This process can be automated easily with a nightly

script.

Nightly maintenance and amp_backup scripts back up the full AirWave data and save the file as nightly_data00[1-4].tar.gz.

In previous AirWave versions, the scripts created both config backup and data backup files. In order to restore the AirWave

data, it is only necessary to have most recent data backup file, and AirWave no longer uses or supports the config backup

file, effective as of AirWave 6.3.2.

Running Backup on Demand

To create an immediate backup:

1. Log into the AirWave system as root.

2. Run the backup script by typing amp_backup.

This creates a backup of the system located in /alternative/databackup.tar.gz.

Restoring from a Backup

To restore a backup file on a new machine:

1. Use your AMP Installation DVD to build a new machine. The new machine must be running the same version as the

AirWave that created the backup file.

2. Copy the nightly_data00[1-4].tar.gz file to the /tmp directory in the new AirWave.
