Once upon a time Jose Lerebours shaped the electrons to say...

So please first: get one of the supertar products. For example one
of those mentioned in

After you have an reliable backup with desaster recovery
running, you can start playing with synchronizing boxes.
(Ever imagine what will happen (to you) if you mix up the boxes...?)
(One small hint: it is relatively complicate to
change the IP-# of an SCO OSR... The IP-# is compiled into kernel...)

You can do that using "cpio" too.
Typically by piping it thru ssh, some tried rsh... others use netcat.
(rsh is on you box, ssh need to be installed, netcat is only a 
sinple program, but i don't know if it is ported to SCO OSR)
Just search on google for "tar rsh ssh remote" 

The advantage of cpio is:
You can be quite sure that all works as expected because 
it is made by the maker of the OS...

The disadvantage is, that it will copy everything it is
told by the "find" command.
But -if told- it too "sees" if file to be copied 
is not newer than the existing.
And too: rsync might not bring the time advantage you may expect.

If on the master system databases are running, make sure
that you can really access the files!
Best you should shutdown the database while copying.

"rsync-backup" or "dirvish" maybe be usefull?

Image what will happen if a process destroys some of the master
files and your script is copying those files to the "backup" system...
both systems are wished...

rsnyc does not need an "install" for those backup jobs.
Just make sure that it can be found on every machine in 
the same directory and you have some kind of "remote shell" access.
Maybe you want the man page on site, but you read them
as well in

You should install the -minimal- SCO development system 
(it's on your server CD) and replace the compiler with gcc.
You need to "hack" the achiver with a link.

Do a search for "Tony Lawrence"

Too have a look into usenet:comp.unix.sco.misc
rsync is currently "on topic" there.
