Eek. Your assumption that your tape device is fd0H1440 is WRONG. That device belongs to drive A (in MSDOS terms) and specifies that it's a HD 1.4K floppy. 

Right off the bat, if you haven't already done this (and it looks like you haven't...) go read the Ftape HOWTO located in /usr/doc/HOWTO, or located on RedHat's Linux Info page. This HOWTO will give you a walk thru on how to set up your tape devices so that they work properly. I can't remember all the details of creating the devices. They should, however be name rftX and nrftX in your /dev direcotry (for rewinding and non-rewinding tape devices). 

The reason you're getting a huge file called tape in your /dev/directory is that the software you're using expects to find an I/O device in /dev/called tape, which points to your tape drive, just like fd0H1440 points to your floppy. Since it either can't find it or it's not properly made, the software iscreating an archive named /dev/tape. You *could* back up this way, and it would work, but hey, you spent the money for the tape, you might as well use it...
