Operating Systems SCO Backup/RAID of HD on Old UNIX Server Post 302956553 by zaxxon on Thursday 1st of October 2015 03:40:23 AM

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.

BOOTCD2DISK(1)							   bootcd utils 						    BOOTCD2DISK(1)

NAME
bootcd2disk - copy a system running from bootcd to a disk SYNOPSIS
bootcd2disk [-i] [-s] [-c <config directory>] [-url <url>] DESCRIPTION
With bootcd2disk a CD build with bootcdwrite can be copied to one or more Disk Partitions from the running cd-based system. Therefore bootcd could be used to make rescue disks. It is also possible to let bootcd2disk automatically find a disk, make partitions on it, copy the cd to the disk and make the disk bootable. bootcd2disk will be available as soon as your system is running from cd. OPTIONS
-i With this option the complete bootcd2disk runs in interactive mode and you can run each function manually. This option is useful for debugging. -v The option "-v" (verbose) adds messages on running. -s This option can be used to disable interactive questions and to try to ignore errors. -c <config directory> The configuration directory which normally is "/etc/bootcd" can be changed with this. -url <url> If bootcd2disk is slow on your system (because of a slow CD/DVD drive or the HP ILO virtual CD interface), you can use an image server to get the image from. bootcd2disk use the SWAP partition of your upcoming system as temporary space and copy the image from the con- figured image server to this partition and use it as image. The image server url is configured with this option. example install from imagesserver: bootcd2disk -url http://192.168.1.1/cdimage.iso Another way the increase the performance is the use of the mounted CD/DVD itself for the copy. The option "-url" is the same, the url starts with "file:///" example install from CD/DVD drive sdc0: bootcd2disk -url file:///dev/sdc0 The swap partition of the upcoming system must have enough space to get the whole image! Currently no other options can be specified on command line. All other configuration has to be done in the config files. FILES
