Mozilla Thunderbird backup - DON'T DO THIS!

Having bought a new notebook with Vista Home Premium I needed to backup Mozilla Thunderbird.

Checking in at a couple of sites, MozBackup seemed a reasonable candidate, also being freeware.

The backup went fine. The restore was a very different matter. It wouldn't or couldn't.

In the end I had to restore manually. Fortunately the backup file was simply a zip file with a different extension, so I changed the extension and extracted the files with WinZip (as Vista's zip utility also had problems.)

Finally I manually moved the necessary files and folders into place; however to add to the insult Thunderbird doesn't help at all at finding WHICH file to restore. Put simply both Thunderbird and MozBackup are sods where backup and restore are concerned.

I do still use Thunderbird because it's pretty good at it's job, but next time I upgrade my hardware I'll either transfer everything to Windows Vista Mail or I'll buy a well-researched backup program.

I really do not understand why, though, none of Mozilla's software appears to come with a proper backup program included with the software when most other major programs DO! What's so special about Mozilla that they can ignore the users' needs?
