What exactly do you mean by "increment backup of emails"? I assume you must be using pop3 protocol for mail, so all your emails will be stored in ~/.thunderbird/rqxrmg4n
.default/Mail/subfolders, (your alphanumeric.default profile folder will be different to mine shown here).
If you backup regularly your /home to another disk or somewhere else, using rsync or similar application, those mail folders will only be copied to the backup if they have changed.
Is that the kind of thing you're looking for?
