    Is there any program out there (preferably under MacOS) that can do an
image copy of an entire SCSI partition, from one drive to another?

    I have a site license for 10 computers to run A/UX. I have one of them
set up in very specific way (local accounts, all the local files needed for
X11, directories for mounting NFS, local hosts files, man pages, etc etc).
I want to see if I can "clone" this setup by copying the entire root partition
(slice 0) from the internal drive, to an external, and copy it back into
the rest of the computers. This would facilitate the process of setting up
all the computers (better than going one by one trying to redo each change).
It will also provide me with a backup copy from which to restore the system
when A/UX crashes -  and in the "open" environment where the computers are,
A/UX crashes a lot!

    I have looked all over for any program that will do this with no luck.
What it basically has to be able to do is to perform an image copy of a SCSI
partition. It *cannot* be a file copy, since it is an A/UX partition. Anyone
have any clues as to where such a program may be available?

    Since I want to be able to use this copy to restore A/UX, doing it from
A/UX is not very helpful (I'd need to be running it to install it!). Still,
if that is the only option left to me - how could I do it? I have tried
several ways.... a staright file copy is no good because it would change all
the owner/group/permissions at the destination. Using dcopy would require
the root file system to be unmounted. Cpio would work, if I could get a
recursive list of all the files in the partition, with full paths - "ls"
does not provide any listing like that. Any other possibilities I can see
would require either having TWO copies of the file system on the external HD
(a waste!), or some extra hardware I do not have. Any options I overlooked?
Any way to make the previous alternatives work?

    Please email any responses, and I will gladly forward any info I receive
to anyone who's interested, or post a summary. Thanks in advance...
