I can't have it as external, the simplest thing would be to copy it over the
network, for me
I could do that like this:
`dd if=/dev/sd3i | ssh destination-computer "dd of=/tmp/sd3copy"`
or even
`dd if=/dev/sd3i | ssh destination-computer "dd of=/dev/sdXi"`
where sdXi is the crypto volume of the destination-computer's receiving drive

If you think this approach is okay, how do I proceed? If something like 2nd
approach is not possible, then the 1st approach is like a filesystem written to
a file? If so isn't there a tool to convert a file to a filesystem?

Am I missing anything?

What do you mean?
