A technique that I use on a regular basis to copy from one partition
to another is the following:
...say i want to copy my root directory to a new harddrive that I
have now mounted on /mnt. I have a /home mount and a /usr mount and
I don't want to touch those.
one the dest. drive is mounted
find / -xdev -depth -print | cpio -pvdumB /mnt
It is quick, safe, keeps permissions, blah...blah! I have used it
quite a bit!
Hope it helps.
