!!! Remote "copying" containers.
We want to be able to have remote backup of the containers.\\
A very simple straight-forward way is :
* on the target host, remove (or rename temporary) {{/var/lib/lxc/cn1/rootfs}}
* on the source host, issue :
{{{
root@apollo:/var/lib/lxc/cn1# tar -c rootfs | ssh 10.0.0.164 tar -x -C /var/lib/lxc/cn1
}}}
This will copy the complete root filesystem of container {{cn1}} to the other host at 10.0.0.164.
There is always at least one file to change after this action, and that is the ip address in {{/etc/network/interfaces}}
