Running Backup On Demand; Restoring From A Backup; Using Awms Failover For Backup - Dell PowerConnect W-Airwave User Manual

Regularly save the data backup file to another machine or media. This process can be automated easily with a
nightly script.
NOTE: Nightly maintenance and amp_backup scripts back up the full AMP data and save the file as nightly_data00[1-4].tar.gz. In
previous AWMS versions, the scripts created both config backup and data backup files. In order to restore the AMP data, it is only
necessary to have most recent data backup file, and AWMS no longer uses or supports the config backup file, effective as of
AWMS 6.3.2 and later AWMS versions.

Running Backup on Demand

To create an immediate backup:
1. Log into the AWMS system as root.
2. Run the backup script by typing
This creates a backup of the system located in /

Restoring from a Backup

To restore a backup file on a new machine:
1. Use your AWMS Installation CD to build a new machine. The new machine must be running the same
version as the AWMS that created the backup file.
2. Copy the nightly_data00[1-4].tar.gz file to the
A file transfer client that supports SFTP/SCP for Windows is WinSCP:
WinSCP allows you to transfer the nightly00[1-4].tar.gz file from your local PC to the new AWMS using the
secure copy protocol (SCP).
3. Log onto the new server as root.
4. Change to the scripts directory by typing
5. Run the restore script by typing
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 AWMS Failover for Backup

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