Re: [gentoo-user] Copying a disk

[Robert G. Hays]

tar does have one drawback that may or nay not matter to you -- it needs 
somewhere to put the tarball.  The obvious answer is to put it on your 
new, blank, drive.

However,
       cp -dpRa  /* /mnt/<newdrive>
-does- do the job properly; it complains that it is skipping the 
recursive copy of /mnt/<newdrive>, and gets it done.

As for speed, I've used both techniques, and I think the above cp is 
faster, but I could be wrong... YMMV.

And if you have a separate /boot partition, that probably needs to be 
copied as a whole partition, not a system full of files (in my experience).

Best,
rgh.

Do not use cp, it doesn't preserve permission bits.
     

cp -a does and is much faster than rsync.
   

if you want to populate new hard drive w/o anything on it. I suggest you
use Tar as it is faster and it uses block copy rather than char-by-char.
