Your tape backup program "wants" to communuicate the fact that it needs you
to insert a second tape by opening and writing to the pseudo device
"/dev/tty." Apparently this program is not running "on" a terminal (i.e.
cron) so /dev/tty is not "connected" and as such fopen returns ENODEV. A
better approach would be to write to /dev/console which should exist (I
assume Linux has a /dev/console!) This should be configurable or it's part
of a bug(feature) report.

Your tape driver looks like it does not want to eject a tape that has not
been rewound. Try rewoffl or whatever it really is or use /dev/st0.
