Looks like the previous poster's reply got munged because he used angle brackets. That should have read:

Code:
tar cvfp - <directory / file to backup> | rsh <target hosts> " cd <target directory> ; tar xvfp - "

The only modification i would make would be to change it to:

Code:
tar cvfp - <directory / file to backup> | rsh <target hosts> " cd <target directory> && tar xvfp - "

The "&&" after the cd command ensures that the files are not extracted if for some reason the cd command fails. If, for example, you make a typing mistake in the path, the files would be extracted in your home directory instead which is probably not what you wanted.

virt-tar-in(1)						      Virtualization Support						    virt-tar-in(1)

NAME
virt-tar-in - Unpack a tarball into a virtual machine disk image. SYNOPSIS
virt-tar-in -a disk.img data.tar /destination virt-tar-in -d domain data.tar /destination zcat data.tar.gz | virt-tar-in -d domain - /destination WARNING
Using "virt-tar-in" on live virtual machines can be dangerous, potentially causing disk corruption. The virtual machine must be shut down before you use this command. DESCRIPTION
"virt-tar-in" unpacks an uncompressed tarball into a virtual machine disk image or named libvirt domain. The first parameter is the tar file. Use "-" to read the tar file from standard input. The second parameter is the absolute target directory to unpack into. EXAMPLES
Upload a home directory to a guest: virt-tar-in -d MyGuest homes.tar /home JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-in" command. For anything more complex than a trivial copy, you are probably better off using guestfish directly. OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options. SEE ALSO
