I would suggest using dump (and restore if you need something recovered) if you can because cp may not preserve everything appropriately. or dump | restore if you are trying to build the file system on to the other disk. I wonder also about your choice of devices, but I don't know how you created them or mounted them. Actually, I would use their mount names rather than devices anyway. Or am I missing something here? Using dump[/restore] won't speed anything up, but it would make sure it is usable later. ////jerry > > Cheers, > > Richard >
