I partitioned the internal hard drive of my MacBook to 2 partitions, one for the System (Mac OS and Software), the second partition for the user data. On the second partition there is some shared data accessible by all users, and the home directories for 2 user accounts encrypted with FileVault.

Now, my problem is: the whole second partition does not get backed up by Time Machine. I already checked out the information in this thread
http://discussions.apple.com/thread.jspa?threadID=2022065
But did not succeed. The internal drive and the external backup drive have both GUID partition tables. All drives are formatted to Mac OS Extended (Journaled).

I would greatly appreciate any help or hints.

    Hi, and welcome to the forums.

    Why have you separated OSX from your user data? That's usually counter-productive on OSX.

    The second partition is OX Extended (Journaled), and is not in the exclusion list in TM Preferences > Options?

    If so, the preferences file may be corrupted. Try a "full reset" per #A4 in the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.

    Home Folders encrypted with FileVault are not backed-up normally. They're only backed-up when you log out. You should see a message when that happens. And all you'll see in Time Machine is the sparse bundle containing the encrypted home folder, not the normal files and folders (that's kind of the whole point of encrypting it).

    Are you sure you really need to have everything in both those home folders encrypted? That's vast overkill for most folks, and makes browsing your backups impossible, and restoring anything very difficult.

    Besides changes not being backed-up every hour, you cannot browse or restore individual files from your backups.

    An alternative is to make an +encrypted disk image+ via Disk Utility (in your Applications/Utilities folder), and put only your sensitive documents there. Then everything else in your home folder will be backed up normally, and you can browse the backups and restore individual items.

    Bingo! Saw this about a year ago.

    Time Machine automatically excludes a number of system/work items, including the folder named "home" at the top level of any disk/partition it's backing-up.

    Rename it to anything except dev or home or net and your backups will likely work fine.
