$ diskutil info /Users/username

The fun part is – IncludedVolumes one can put in best using Plist Editor, as described in the article. For IncludedVolumeUUIDs it is easier to edit plist file with TextWrangler. Without [u]both[/u] of these entries Time Machine won’t pick up the VileVault directory for backup.

Oh and it works! Tested!

In the first paragraph, you say to “open com.apple.finder.plist, located in your user’s /Library/Preferences folder”

…My system did not have such a file. I think you meant to open the one in the user’s Library, at /Library/Preferences (in UNIX speak, ~/Library/Preferences)

….Later in the tutorial, you say to “make a back up of com.apple.TimeMachine.plist, located in /Library/Preferences, and then open the original file”. This time you really did mean root of the drive (/Library/Preferences).

THANKS for posting this awesome HowTo. It worked for me, and totally saved my behind. I use a complicated setup similar to the one in this post:

Mounted (i.e. open) disk images were backed up via Time Machine automatically in Leopard 10.5, but apparently this behavior was changed in 10.6. I don’t feel comfortable backing up the sparsebundle itself, since it is open all the time, and read/write operations will not necessarily synchronize. Now, thanks to your hint, I’m back to the way things were.

BTW: I back up to an encrypted sparsebundle as my Time Machine destination drive, so my encrypted data *stays* encrypted at the end of the day.

Thanks again!
