Now that we have Filevault 2, is it possible to run Time Machine backups without having to log out (as I understand was necessary with Filevault 1)?

I have searched everywhere, and have been unable to confirm it one way or the other.

I'm curious about this too. I guess I'd like to encrypt my internal disk as well as my external drives (including my time machine disk), but I'm wondering if I have to log out as well or if I'll see a performance hit.

I am using Filevault 2 on my internal disk to encrypt it as well as my external Time Machine drive(which I had to re-partition to encrypt it). Using the previous version of Filevault, it was a pain but now, I can backup while still being logged into my computer without a noticeable drag on the OS. Hope this helps.

Can you explain how you're doing this?

Filevault 2 is completely transparent to all software, including Time Machine. You do not need to log out for TM backups to occur.

As been said, you do not need to log out anymore, and since it encrypts everything (they changed it to smaller packages too?), Time Machine does not make a backup of your entire Home Folder every time you make a backup, but seems to work similar to an un-filevaulted backup.

It is definitely nice to see that we don't need to log out to back up the HD and both drives will be encrypted.

Any idea why my HD size is about 30GB but all my Time Machine backups over the last 12 hours only add up to 20GB? Where is the other 10? The initial backup was only around 17GB ...

An update:

I did turn on Filevault, and it was able to continue Time Machine backups without logging out.
