I got to know about this command from Chris Gibson's blog, i would recommend all you AIX folks to visit his site once
Purpose of this command.
Performs the operations for backing up the virtual and logical configuration, listing the configuration, and restoring the configuration of the Virtual I/O Server.
The viosbr command can be run only by the padmin user.
Pre –Reqs
This vios version should be at 2.1 with fixpack 22 applied on the server.
$ ioslevel
2.1.2.10-FP-22
For more information about the viosbr please check the man page, this will give you the default backup location and user defined location with the options.
$ viosbr -view -list
/home/padmin/cfgbackups/ not found
$ mkdir cfgbackups
$ viosbr -backup -file bvio83_vios_config_bkp
$ viosbr -view -list bvio83_vios_config_bkp.tar.gz
A tar/gzipped file was created in the cfgbackups directory.

The –restore and –validate flags validate the devices on the server against the devices in the backup file.
$ viosbr -restore -file bvio83_vios_config_bkp.tar.gz -validate

This tool looks like a great way to backup and restore your VIOS configuration.
Of course backupios will also do this but it will take an image of the entire system not just the virtual and logical mappings.
