I am not familiar with SCO, but the command in the crontab will "just" copy the files and directories to the device /dev/rct0, which is most probably your attached tape drive.
This type of backup is not bootable. It misses the boot sector, filesystem structure etc. which is needed, to have bootable backup. It will have your business data in there though.

You could do a copy of the disk with the command dd which will create a file of 9GB, as larges as your disk is, because it copies all bits of your disk. It could be restored with using a bootable medium that gives you a shell from where you can issue dd again, to restore the backup.
The hardware sounds x96 compatible so you could for example try Knoppix (KNOPPIX - Live Linux Filesystem On CD) which is a free Linux bootable system with desktop etc. to issue restore.

Here is some guy that tried something similar:
SCO 6. Backup & Restore from USB

Maybe it is an option to get a modern x386 PC or server hardware, install a later version of SCO Unix and migrate your application overthere. It could be it is possible by simple copying it's needed files over to the new installed machine. Though I saw the latest release of SCO is 2009 Smilie

OpenServer X seems to be the continued SCO Unix but I have no clue how compatible to each other.

vxconfigbackupd

vxconfigbackupd(1M)													       vxconfigbackupd(1M)

NAME

       vxconfigbackupd - disk group configuration backup daemon

SYNOPSIS

       vxconfigbackupd [-l]

DESCRIPTION

       The vxconfigbackupd daemon automatically backs up information about a disk group's new configuration whenever the configuration is changed.

OPTIONS

       -l	 Logs backup daemon activities to the file /etc/vx/cbr/bkdaemonLog.

FILES

       /sbin/init.d/vxvm-recover
		 Startup file for vxconfigbackupd.

       /etc/vx/cbr/bk/dgname.dgid/dgid.dginfo
		 Location of backup file for disk group information.

       /etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo
		 Location of backup file for disk attributes.

       /etc/vx/cbr/bk/dgname.dgid/dgid.binconfig
		 Location of backup file for binary configuration copy.

       /etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec
		 Location of backup file for configuration records in vxprint -m format.

NOTES

       The vxconfigbackup command can be used to back up a disk group's configuration manually at any desired time.

       The  disk  group  configuration	backup and restore utilities do not save any data in the public region. This includes file system or other
       application data that is configured within VxVM objects.

       When a disk group is destroyed, its configuration backup information (including the backup directory) is also removed.  The only  exception
       to this behavior is when the disk group is in the precommit state of restoration.

       The  backup  directory should be large enough to accommodate copies of all the currently imported disk groups. The minimum recommended size
       of the backup directory is P * (N + 1) megabytes, where P is the private region in megabytes (by default, 32MB), and N  is  the	number	of
       disk  groups. The additional P megabytes is required to hold a temporary copy of the disk group configuration when a disk group is imported
       or a configuration change is made.

       The default backup directory is /etc/vx/cbr/bk.	The location of the backup directory can be configured	by  using  the	vxconfigbackup	-l
       backup_directory_path command.
