Easily encrypt Time Machine backups
Authored by: noworryz on Oct 07, '10 09:56:22AM

This hint really only applies if you want to store your files unencrypted on your computer but have them encrypted on the backup volume, which is an odd thing to do.

Without using this hint, users of File Vault will have their home directories backed up encrypted on a Time Machine volume when the disk is connected and they log out or when another user is logged in.

Also, if a user creates an encrypted disk image on the computer (using Disk Utility) and uses it to store sensitive files, it will be continually backed up encrypted on a normal Time Machine volume.

Easily encrypt Time Machine backups

Maybe not necessarily. My computer is fairly well protected by the login password, but anyone could just plug in the backup drive and access the data.

Also, you might not care so much about having local data encrypted, but I wouldn't backup remotely without encrypting, especially if the server is owned by someone else.

What if someone puts your computer in target disk mode?

That's what the firmware password is for.

Even the firmware password can be reset if you have physical access to the machine. If you have access to the RAM, it's very easily reset.
