A tar-hoz ez még jól jöhet:
An archive name that has a colon in it specifies a file or de‐
vice on a remote machine. The part before the colon is taken as
the machine name or IP address, and the part after it as the
file or device pathname, e.g.:--file=remotehost:/dev/sr0
An optional username can be prefixed to the hostname, placing a
@ sign between them.By default, the remote host is accessed via the rsh(1) command.
Nowadays it is common to use ssh(1) instead. You can do so by
giving the following command line option:--rsh-command=/usr/bin/ssh
The remote machine should have the rmt(8) command installed. If
its pathname does not match tar's default, you can inform tar
about the correct pathname using the --rmt-command option.
