What script do I run from SSH to restore a saved backup .zip file?

How to import backup file on the command prompt:

# cd /etc/multiconf/backup/

# /etc/multiconf/scripts/bkupmain importbkp backup_filename.zip

backup_filename.zip are the backup configuration that are stored in the /etc/multiconf/backup directory. Make sure your backup file is the same version as the current running software.
