How to make a system backup of a VIOS

To create a system backup of a Virtual I/O Server (VIOS), run the following commands (as user root):


# /usr/ios/cli/ioscli viosbr -backup -file vios_config_bkup 
-frequency daily -numfiles 10 
# /usr/ios/cli/ioscli backupios -nomedialib -file /mksysb/$(hostname).mksysb -mksysb


The first command (viosbr) will create a backup of the configuration information to /home/padmin/cfgbackups. It will also schedule the command to run every day, and keep up to 10 files in /home/padmin/cfgbackups. 

The second command is the mksysb equivalent for a Virtual I/O Server: backupios. This command will create the mksysb image in the /mksysb folder, and exclude any ISO repositiory in rootvg, and anything else excluded in /etc/exclude.rootvg.
