Thanks for the PM, but it would be better if you respond in the thread so that others may also benefit.
So you have two SCO 5.0.5 machines that you want to have mirror each other.
If you are looking for a magic bullet, forget it.
SCO have solutions based on 5.0.7 and Unixware, that will provide this kind of product if you need minute by minute redundancy.
If you can live with once per hour or per day mirroring then use either NFS or FTP to copy the changed files from the primary system to the backup system.
An alternative is to add transaction logging to your application on the primary system, and have a background process on the secondary machine post those transactions to the data files on that machine.

JIGDO-MIRROR(1) JIGDO-MIRROR(1)
NAME
jigdo-mirror - Maintain a mirror of images offered with jigdo
SYNOPSIS
jigdo-mirror [ config-file ]
DESCRIPTION
See jigdo-file(1) for an introduction to Jigsaw Download.
jigdo-mirror is a script intended for people who want to offer direct HTTP or FTP downloads of files for which only the jigdo and template
files are available.
As the first step of using jigdo-mirror, you need to set up normal HTTP/FTP/rsync mirroring both of the `.jigdo'/`.template' files and of
the parts that are needed for the reconstruction of the images. For example, in the case that you want to mirror Debian CD images with
jigdo-mirror, you need a mirror of the `.jigdo'/`.template' files and a Debian mirror on the local machine.
At regular intervals (preferably immediately after the normal mirroring has finished), schedule a run of jigdo-mirror. It will search
through a given directory for any `.jigdo' files and attempt to create all images offered by each file.
The script requires you to set a number of variables - please refer to the start of /usr/bin/jigdo-mirror for a description of each of
them. Since /usr/bin/jigdo-mirror will be overwritten whenever you upgrade jigdo-mirror, it is highly recommended not to change the set-
tings directly in this script. Instead, personal settings should be saved in a file called .jigdo-mirror in your home directory, or in a
different file whose name is then passed to the script as its first (and only) command line argument.
