Linux and data storage?

[Janina Sajka]

No, you can't, not in any useful way.

However, I'm not aware that security is the largest concern here. We're
talking about a one time file transfer. I would certainly not suggest
ncftp for regular use backing up data because the password does get sent
in the clear.

Frankly, building the .tar.bz2 file in /tmp might be considered
insecure, as anyone might get at it there.

The background transfer of ncftp is a very nic feature, though. You can
get similar securely with nohup and scp or rsync.
