Structure update
Using the backup tool, create a file capable of updating system changes (new tables and global lists, etc.) without losing system data. Example of use:
Upgrade the system developed on several clients without having to alter all system installations. (www.siteinstall.com/client1, www.siteinstall.com/client2, www.siteinstall.com/client3...) all subdomains have the same system installed but operating in isolation. The objective is just to upgrade and update a file using the bkp tool and the changes would be applied without losing data and this update could be used in all domains where the system works in isolation.
Thanks
