- If the backup medium is another disk, mem stick, DVD, or CD-ROM, you can actually mount that backup container file whenever you want without ever copying it back to the original hard disk.

That's the simple view of TrueCrypt. There is lots more. For example:
- Anyone examining your system or your disk can tell that you use TrueCrypt, and can probably even identify the container files.
- However, you can host a TrueCrypt volume within another truecrypt volume in a manner that makes the internal volume both hidden and undectable even if the outer volume is mounted and visible. Really cool. The TrueCrypt people call this "plausible deniability," and consider it quite important.
- Example: An adversary points a gun at you and demands to see your encrypted files. You can give them the password to the outer encrypted volume without ever revealing that an inner, hidden volume even exists. It's invisible. I don't actually see the need for a hidden volume in my business, but evidently some folks do.
- You can host a truecrypt volume on a public computer, or another person's computer, without installing any software on that computer, so your encrypted files are portable.
- You can tell TrueCrypt to mount certain TrueCrypt volumes automatically at bootup, though you will be required to enter a password to complete the mounting process.
- TrueCrypt allows you to use any of eight different encryption algorithms and three different hash algorithms, making decryption by an adversary even more difficult.
