Backing up all Thunderbird data automatically - which folders do I actually need to copy to my NAS?

more options

I'm struggling to understand where Thunderbird stores everything on a Windows computer so that I can use my incremental automated backup system to keep things backed up.

This support article :

[- Where Thunderbird stores your messages and other user data]

only mentions about the <user>\AppData\Roaming\Thunderbird\Profiles folder but there is also a <user>\AppData\Local\Thunderbird\Profiles folder that appears to be used and needed.

There is a ton of other conflicting 3rd party information out there so I'm hoping for a definitive answer here.

My question is : Can I backup just the '<user>\AppData\Roaming\Thunderbird\Profiles and <user>\AppData\Local\Thunderbird\Profiles and be assured that I will be fully able to recover my email client in the case of needing a complete reinstall ?

You only need to backup what the article says, which I'll link here for reference because the link you posted is malformed:

https://support.mozilla.org/kb/profiles-where-thunderbird-stores-user-data

The other profile folder you see under a Local folder is for temporary and cache files, and is kept in a separate directory precisely so you can backup the relevant data without including that.

You may want to backup the whole Thunderbird folder two levels above the profile folder, but definitely not the other part.

Sorry about the link - I noticed that as soon as I submitted the question but apparently editing posts is not a thing here?

Thank you - that helps a ton !

For reference, I've now figured out that my problem trying to migrate from one computer to another (that got me on this path in the first place) is that "way back when" I was short of disk space so I moved the Local POP3 folders to a different drive that had space. You can do that deep in the settings of an email account but if you forget to also back up that folder you can lose a lot. PEBKAC of course.

I do it all the time. You should be able to see a 3-vertical-dots button to the right of every post. If the post is yours, editing it should be one of the options available there.

That was the first place I checked but all I get is the option to "Quote". I've attached a screenshot.

Maybe it's because I'm using a new account ?

[EDIT : well, I can edit this comment but still not my original post? ]
