    I have been trying to encrypt my 3TB time machine with file vault 2 (my os is 10.7.2) with no success, I always get an error message. Oddly at work, the encryption was successful on my 1TB time machine drive.

    Looked up apple support and many people have the same problem without any solution (apparently Lions has bugs or fleas!)

    Does anybody have a solution?

    Is the disk MBR formatted? If so, then you cannot have a partition larger than 2 TB. Try using the GUID partition instead.

    Not familiar with these terms but disk utility tells me that it is already GUID...

    Bus de connexion : FireWire
    État d’écriture : Lire/écrire

    État S.M.A.R.T. : Non géré
    Schéma de carte de partition: Tableau de partition GUID

    Not to take this off topic, but isn't risky to encrypt your back ups? I'd rather not risk my ability to restore my system.

    What error message are you getting, and is the drive empty at the time. Perhaps there's not enough free space to encrypt the drive.

    It does not make sense, to have a FV2 encrypted machine, if any burglar or other thief can steal your unencrypted backups.

    One can only assume the OP's main drive is also encrypted, hence the need to encrypt the backup as well. Otherwise… I can't think of any reason to do so.

    Yes it is! Because if you have to ever send the drive in for repair or Professional data recovery from what i have been told it isn't possible to get into the encrypted disk.

    If the pass word is lost - no back doors to get in unless apple stores the recovery keys, i know they do if you encrypt your macs hdd, not sure of TM drive

    Thanks a lot, it does help. I guess I should not use a "Sparsebundle” superior to 1TB as lion cannot handle encrypting to larger sizes? (I believe that is the problem that I am facing, correct?)

    Not sure - I am far from a Mac expert. I just followed the instructions on that site and it is working for me so far. But my Time Machine backup partitions are limited to 600 GB and 300GB (2 macs backing up to the NAS).

    The whole POINT of encryption is to not allow Apple, or anyone else, access to your data.

    I *love* FileVault 2 because I can solidly encrypt my disk and know that if my machine fails in warranty and I have to send it to Apple, they can't access my data. In the past I would have had to remove the hard drive and zero it, and even that wouldn't have been possible if it was the actual hard disk that had failed.

    If you're that nervous about losing your passphrase, write it down on a piece of paper and lock it in a bank vault or something. :)

    For those interested, after updating to 10.7.3 I have been able to encrypt my 3Tb Time Machine drive seamlessly.
