Mozilla Thunderbird and Time Machine
I would like to migrate from Outlook 2011 to Mozilla Thunderbird, but know that in the past Thunderbird used to store all emails in one large database. This obviously is not a good situation for Time Machine, because a single email will result in the entire database being backed up every hour. Since I currently have over 57000 emails that must be preserved the database file will be huge.
Long ago I read that the developers of Thunderbird was planning on creating a "one file per email" kind of storage system that will allow Time Machine to incrementally backup the latest email messages and not the entire database every single time.
I cannot find any info on whether this was implemented or not, so my question is: Can a Thunderbird user please check how emails are stored and let me know if it's a single database or multiple files?

There's a trick I learned ages ago for dealing with this: If you symlink a large file from a sparsebundle disk image, then only 8MB of the file will change at a time. It sorta fakes block-based backups. Not every app can cope with a symlink though, but most of them can. I can help you set it up if you want to try it.

hdiutil create -size 20G -fs JHFS+ -volname "My Volume Name" ~/SparseData.sparsebundle
ln -s "/Volumes/My Volume Name/MovedFile.dat" "/path/to/original/location/MovedFile.dat"
Of course, for things like a VMWare image, you can just specify that you want the image stored on the sparse bundle during creation. Much simpler that way.
