Encrypted backup of whole-disk encryption Arthur T. 03-13-2008

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.
