    Encrypted backup of whole-disk encryption

    I have encrypted virtual disks. When I back up the OS files
    that hold them, the backups are equally encrypted.

    I've downloaded TrueCrypt. When I get brave enough, I'm
    going to implement its whole-disk (or whole-partition) encryption.
    Is there any reasonable way to back up the data so the backup is
    encrypted? (Is there any *free* way to securely back up the
    data?)

    I'm running Win2K. I normally back up to DVD RW.

    1. trivial, obvious way: Use dd.exe or a more complex imaging software to
    create an image of the raw disk, then burn it.

    2. easier, more efficient way: Simply backup filewise from the running
    system and encrypt the files

    Running a system with known unpatched vulnerabilities is something TrueCrypt
    can't defend against.

    It is quite complex and it needs quite a bit of time to learn, but
    anyway, here it goes:

    Thank you. That looks like what I'd want. It's going to be
    scary to test the restore, but, not as scary as using a new backup
    program and *not* testing the restore. (It's also a good thing I
    kept my C: partition at 4GB; it'll fit on a DVD.)

    Thanks again for the link. I probably won't report back on
    success or failure because it'll be a while.

    As it turns out, I probably will not be using that utility.
    Truecrypt encryption of the OS partition does not support Win2K,
    which is what I'm running. I don't expect to downgrade to XP or
    Vista, nor do I expect Truecrypt to start supported "older" OSes.

    It fully support Windows 2000 SP4 with the Update Rollup Package, and you
    compile it for this platform yourself.

    Why should XP be a downgrade?
