This is a big problem that people everywhere are running into.  The only
thing I can suggest is figure out what the _most_ important data you have
is and keep that backed up.  If everything is extremely important to you,
then, for 300GB, expect to spend a year's salary to back it all up :)  

A reasonable DLT drive is at least $3000 and for media with compression up
to 80GB per tape is roughly $100 per tape.  You do the math :)  There's
really no other solution.  Anything other than tape is just too slow to
back up that much data in a day.  Even running through 4 80GB DLTs is going
to take a _long_ time (most of the night).

If you really care about your data that much, you won't just back it up to
a RAID.
