If your Qube is a 2700 then you can get inside the backup file by changing
it .qub suffix to .tar.gz and opening it with WinZip.  This will say that
the "Archive contains one file: backupfile.tar  Should WinZip decompress it
to a temporary folder and open it?" - reply "Yes". All the individual files
will be listed and you can extract whatever you want.

Unfortunately, the Qube2 backup file has some extra material inserted and
so, the above technique does not work directly.  Jeff Bilicki supplied the
following perl script for overcoming this difficulty - I haven't used it
myself.

Extract from Jeff Bilicki's response (25 August 1999) to my query follows:

If you run the following perl script against the tar it will strip out
the Cobalt specific headers and leave just the tar ball.   I tried this
on a couple of backup files, it seem to work ok even though tar gave
errors on exit.

#!/usr/bin/perl

use strict;

my ($infile);
my ($outfile) = "out.tar.gz";

if (@ARGV) {
        $infile = $ARGV[0];
} else {
        print "usage: stripheader.pl <file name>\n";
        exit 1;
}

open (INFILE, $infile) or die "Can't open: $!\n";
open (OUTFILE, ">$outfile") or die "Can't open $!\n";

while (<INFILE>) {
        if ( /^$begin/ ... /^$end/ ) {
                next;
        } else {
                print OUTFILE $_;
        }
}
close(INFILE);
close(OUTFILE);
exit 0;
