I am running a system under version 4.23, using an Adaptex SCSI controller.
Does anyone know what tape drives (20-30 gig) that I can attach, and if
there is any backup software that runs in QNX?
Hi Kerry,
Don’t think it should matter. As long as the adapter can see the tape drive
we should be able to interface with it.

I run a Sony DAT tape backup drive (4G variety) and it works fine. Here’s
the script that I use for backups… YMMV 
#! /bin/sh
This script file is responsible for performing the daily backup
procedure. It runs in one of two modes. On the first of the
month, it backs up the entire disk (mounted on /) to $Backup/YYMM.Z.
(Where $Backup is the variable representing the backup device or
directory, and YYMM represents the year and month).
Every day, apart from the first of the month, it backs up any
files that have changed within the last day to $Backup/YYMMDD.Z.
Files contained in /etc/noback.table are explicitly not backed up.
These are typically news history files, or large libraries that can
be readily regenerated.

Some variable definitions
Backup:
this is the backup device (DAT drive = /dev/tp0, for example)
Backup=/dev/tp0
Prepare for run
cd /
Determine if we need to do the entire month backup, or just the
incremental.
day=date +%d
month=date +%m
if test “$day” = “01”
then
Monthly
echo Monthly Backup to $Backup on date >/tmp/backup.report
tape rewind erase
echo Tape initialized at date >>/tmp/backup.report
find . /source/ ! ( -path ./usr/spool/news -prune ) -type f |
grep -vf /etc/noback.full.table |
tee -a /tmp/backup.report |
pax -w > $Backup
tape writefm rewind
echo Done on date >>/tmp/backup.report
mail -s"Monthly Backup Report" root </tmp/backup.report
else
Daily
echo Daily Backup in progress to $Backup on date >/tmp/backup.report
tape rewind
sleep 2
tape eod
sleep 2
echo Tape rewound to EOD on date >>/tmp/backup.report
find . /source/ ! ( -path ./usr/spool/news -prune ) -type f -ctime -2 |
grep -vf /etc/noback.table |
tee -a /tmp/backup.report |
pax -w > $Backup
tape writefm rewind
echo Done on date >>/tmp/backup.report
mail -s"Daily Backup Report" root </tmp/backup.report
Check to see if we should prompt the operator to change a tape
if test “$day” -gt “28”
then
echo Remember to change the tape RSN!!! >/tmp/x.x.x
mail -s"CHANGE THE TAPE!!!" root </tmp/x.x.x
rm /tmp/x.x.x
fi
fi
rm /tmp/backup.report
exit 0
