I am currently backing up "Program Files (x86)\SmarterTools\" and "SmarterMail\Domains" excluding "Index" folders.

 

However I don't wish to backup the actual mail. I'm just interested in the configuration. So if I ever need to recover, I can just restore all users and domains, but I could care less about the actual email. All users should be offloading it via POP3 anyway.

 

What can I exclude from backups to accomplish this, while still enabling a successful restore?
