Backup/RAID of HD on Old UNIX Server

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

bdb.db0
BDB.DB0(5) AFS File Reference BDB.DB0(5) NAME
bdb.DB0, bdb.DBSYS1 - Contain the Backup Database and associated log DESCRIPTION
The bdb.DB0 file contains the Backup Database, which records configuration information used by the AFS Backup System along with cross- indexed records of the tapes created and volumes dumped using the Backup System commands. The bdb.DBSYS1 file is a log file in which the Backup Server (buserver process) logs each database operation before performing it. When an operation is interrupted, the Backup Server replays the log to complete the operation. Both files are in binary format and reside in the /var/lib/openafs/db directory on each database server machine that runs the Backup Server. When the Backup Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its copy of the bdb.DB0 file matches the copy on the other database server machines. If not, the Backup Servers use AFS's distributed database technology, Ubik, to distribute to all of the machines the copy of the database with the highest version number. Use the commands in the backup suite to administer the Backup Database. It is advisable to create a backup copy of the bdb.DB0 file on tape on a regular basis, using the UNIX tar command or another local disk backup utility. SEE ALSO
