So you have
/dev/hda1 /
/dev/hda2 /usr
/dev/hda3 /var
that you want to clone to /dev/hdc1, /dev/hdc2, /dev/hdc3.
You must mount, the hdc partitions, as, for example:
/backup/hdc/1
/backup/hdc/2
/backup/hdc/3
Thus, when you copy files from hda to hdc, any absolute symlinks,
or symlinks which have relative references that go "up and then
down", will remain pointed back to their original files on hda.
Symlinks that have multiple redirections (with mixtures of relative
and absolute to make things even messier) also must be considered.
