introduction
SCO is a leading provider of UNIX® network server operating systems.
As with most software development cycles, the UNIX® SCO operating system has
been subject to a number of major and minor version releases over time, resulting
in a number of different versions of SCO now being in common use.
SCO ships with a number of native tape drivers ("alud", "arad" and "slha"). The
particular SCSI host bus adaptor (HBA) used on your system determines which of
these drivers is used to control SCSI peripherals such as tape drives. For further
details, refer to the answer to the question
"How do I know what disk drivers I am
using at the moment, and what drivers do I need for running tape backups?"
SCO does not give native support for the HP SureStore DAT24x6 autoloaders.
The HP SureStore DAT24x6 autoloaders can be supported instead by using the
"mtx" utility supplied by Hewlett-Packard on the HP SureStore CD-ROM disk. For
details, refer to the answer to the question
"Why does my device not work
correctly with ISV Backup Software, or the SCO in-built backup applet?"
It is clear that, irrespective of the operating system version or tape drive vendor,
problems are sometimes experienced when users attempt to set up SCO systems
to perform tape backups.
This "UNIX SCO Tape Backup Frequently Asked Questions" document attempts
to highlight and resolve issues relative to tape drive backup under the UNIX SCO
environment.
It is recommended that you read the whole of this FAQ document rather than just
specific questions.

native backup applications
There are a number of tape backup applets written for the SCO operating system.
For details, refer to the answer to the question
"How do I use the built-in Tape
Backup applet provided by SCO?"
Note - Ultrium high performance tape drives:
As a general rule, native backup
applications do not provide the required data streaming rate to get the full
performance of your Ultrium drive. We recommend using a backup application,
which provides better memory management as well as other useful features, such
as TapeAlert. HP, Computer Associates, Veritas, Legato and Yosemite all provide
suitable products that have been tested with your Ultrium drives. For the latest list
of backup packages that support your Ultrium drives, please contact your tape
drive or library manufacturer.
