A bunch of smaller files suffers the same problem on a smaller scale.
You're still backing up all the unchanged files in the volume, as well as
all the unused space.

If you script the mounting ... then you truly have no security.  Unless your
script is just "mount this, prompt for password ... mount that, prompt for
password ..." and still requires you to type a password for every volume
mounted.

Honestly I'm surprised truecrypt doesn't support sparseness in linux.  Their
docs say something to the effect of "you can only have sparse files in ntfs,
so it's not available elsewhere..." and that is of course, incorrect.  

To top that off ... I'm pretty sure truecrypt does support sparseness in
macs.  So ... go figure.

I do have one response that sounds promising, but I haven't tried yet, so I
haven't forwarded it here yet.
