Backing up my Thunderbird profile to back up my email (lemmy.ca)

I've blithely assumes that backups / snapshots of my home dir (including my Thunderbird profile) were covering my email. But it occurs to me it may be more difficult than expected.

I have message synchronization on for any folders I care about ("for offline use"). What I was assuming this meant was that if my mail host disappeared or mysteriously deleted an important folder, I would still be able to switch to a backup, start TB in offline mode (via a commandline parameter), and copy those folders to a local folder at which point I could reconnect and drag them back to my new host, a local imapd I use as an archive, or wherever.

But ...would that actually work? Anyone recover email from offline folders? How'd that go?

I've heard the notion that a backup you don't regularly restore is mostly just theater. If you need to feel comfortable that you can restore your backups, then do that. You will need another machine to use, and then just go through the motions.
