With all the news about remote wipe I am wondering if having a backup on an external disk that is connected to my Mac is OK. Or if someone did a remote wipe, would they wipe that disk as well?

To find out, I guess somebody with a good backup and some spare time would need to volunteer. –  myhd Aug 7 '12 at 14:50

If Apple's incredibly vague description of "your Mac" and "the disk" also includes what is attached to it, which anyone might assume — then YES. On the other hand, if fluff marketing jargon and disappearing statements might leave some doubts in your mind, I would say NO. The only way to really know is to do what myhd suggests.

FileVault 2 encrypts your data.

With FileVault 2, your data is safe and secure — even if it falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. Initial encryption is fast and unobtrusive. It can also encrypt any removable drive, helping you secure Time Machine backups or other external drives with ease. Want to start fresh or give your Mac to someone else? FileVault 2 makes it easy to clean data off your Mac. Instant wipe removes the encryption key from your Mac — making the data completely inaccessible — then proceeds with a thorough wipe of all data from the disk.

OS X and iCloud can help find your missing Mac.

OS X and iCloud can help keep your Mac safe even when you misplace it. Sign in to iCloud.com from another computer or use the Find My iPhone app on an iPhone, iPad, or iPod touch to locate your missing Mac on a map. If your Mac is offline when you try to find it, you can ask to receive an email as soon as it makes a Wi-Fi connection. You can also display a message on your Mac screen so whoever has it knows how to get it back to you. And until your Mac is back in safe hands, you can set a passcode lock remotely, or even initiate a remote wipe to delete your personal data and restore your Mac to its factory settings.
