Distro-> Fedora C2

I have 2 hard drives on my linux box, and what I did to backup my system was to "tar" everything into one tar file and store that file on the second drive (separate filesystem).

Then what I did was reformat the main drive so that I could breakout /var and /usr as their own filesystem.

Once reformatted and Fedora C2 reloaded with new filesystem layout, I saved off the new fstab, mtab, and the blkid.tab files, so that when I ran the tar -xvf, it would not try to use the old filesystem layout when rebooted.

Now my question is, in doing this, could I have screwed something else up? Or is there something else that I forgot or needed to do?

Everything seems to be ok, but it just doesn't seem like a clean way of doing it.
