I've always wondered why so many folks use the above construct when a _fast_ less "expensive" solution STM to be something like cd <your source mount point> ; find . <other params you desire> \ | cpio -p<other params you want> /mnt Am I missing something? Just old fashioned? Cpio has all the params you want and can be _very_ fast with the righ parameters. Similar to the above dump/restore set I've seen many use tar/untar equivalents. Just curious is all. > <snip sig stuff> -- Bill
