I successfully installed the Ubuntu server edition on a PC of mine on partition hda1.
Here's how I partitioned the harddisk:
hda1 has 5gb
hda2 has 5gb (currently emtpy)
hda3 has 1gb and is /tmp
The rest is /usr
How can I backup my existing Ubuntu installation into partition hda2? I want to be able to boot from hda2 if the installation in hda1 gets corrupted.
Can I use the same /tmp partition for both installations?
