Dunno about thunderbird, but Eudora has a mail harvesting option (the dialog is initiated by holding down the shift key when clicking on the "check mail" icon) to, among the list of options, "fetch all mail on the server." This will download duplicates of stuff that you have in the mail client, but will also get stuff that has become missing. (If it isn't still on the server, there is no way to get it.) Thunderbird should have a similar option, I would think but the command to execute it might be anything.
There also might be a way in the Gmail web interface to selectively mark messages as "not yet harvested." Is there a status icon for each message? Does right-clicking on the status icon allow you to change it? In Eudora, the status of each message is kept in a status file on the client, so the problem you speak of won't happen. I.e., the restored backup doesn't know anything about what has been harvested by another instance of the mail client.
