Moving Data ufsdump and ufsrestore

[McQueen]

Hello all,

I'm trying to move a large amount of data from one disk to another, I thought I'd back it up using ufsdump and restore it using ufsrestore so I keep the time stamps. Is there a way i can do a backup and restore without putting it to a file or tape?. Basically a disk to disk backup

A "man ufsrestore" has an example of exactly what you're looking for.

 f dump_file  Use dump_file instead of /dev/rmt/0  as  the
              file  to  restore  from. Typically dump_file
              specifies  a  tape  or  diskette  drive.  If
              dump_file  is  specified  as `-', ufsrestore
              reads from the standard input.  This  allows
              ufsdump(1M)  and  ufsrestore to be used in a
              pipeline to copy a file system:
              example# [b]ufsdump 0f - /dev/rdsk/c0t0d0s7 \
               | (cd /home;ufsrestore xf -)[/b]
