SD! with Lion and FileVault 2
With the upcoming release of Lion, I'm wondering how/if SuperDuper! will support FileVault 2 (seeing as how it is full disk encryption). I can't find any information regarding restoring a FileVault 2 encrypted drive (I'm assuming you'll have to boot off a Lion DVD/USB drive to unlock the drive?). I'm wondering if (since SuperDuper! runs while a user is logged in), that any duplication made would be unencrypted (unless backed up to encrypted sparsebundle, of course). Disk Utility shows my disk as "Mac OS X Extended (Journaled, Encrypted)". Any info on this would be great before I turn this on for my everyday MBP's.

This is one of the reasons our Lion support is "initial". We don't know yet. But you'd have to encrypt the backup and use "Smart Update" to get an encrypted result...

Any update on this?

Lion supposed to be released today and I was considering tinkering with FileVault 2. Won't use it if SuperDuper! doesn't work though.

Same answer at present. We just haven't had time to do thorough testing with it. It should work...

Should work meaning it's just copying the un-encrypted files to another disk/sparsebundle? So if one was to restore, the drive would be un-encrypted and the user would have to re-enable FileVault 2?

I know this is new, just wondering what you meant by "it should work".

Encryption is a properly of the underlying drive structure. It's supposed to be totally transparent to us. So, if the drive is encrypted and we copy to it, the result will be encrypted. Similarly, if the source is encrypted and the destination is not, the backup won't be encrypted.

Enabling FileVault 2 creates a second "Recovery HD" partition, that I believe stores the encryption keys (and the login screen that is shown at boot).

I'm interested to hear what others suggest for backing up a FileVault'd system. Do I need to backup the Recovery HD in addition to my encrypted system partition?

I just finished my first pre-FileVault SD clone. Now I'm off to enable FV.

We don't back up (and don't see) the recovery partition...
