so wait a second.... could I put fsarchiver on the server and then:

tar --ignore-failed-read [/mnt/sda1] -czf - | ssh
remoteuser at remote.system"tar -xzf - "| "<fsarchiver command>"

so the tar command will create a tarball and the the pipe will transfer the
tarball to the server and extract it wich the second pipe will feed into
fsarchiver. Is that correct? I have a question: what does the minus sign in
front of the pipes represent?  Well... I know it represents the name of the
tar ball but.... is it the name? Could I put anything in that place?

and then Enriques command  (tar jcf - /path/to/backup|ssh
user at otherbox'tar xf -') would compress a tarball and then create a
non compressed
archive on the server.

You know... I wondered if I could use scp for this. Investigating the man
page reveals that this is the program I want to use. The text of the
command that I should issue I think would be (I want to do this from a
third computer):

scp -Cr user1 at host1:mnt/sda1 user2 at host2:desired/directory/file/name

I don't know if I assigned a user1 or a host1 name. How can I find this
out? If I didn't how would I assign one or change it to a more appropriate
name?

This is fun!
