A dollar or two?  If you can source BR Media for a dollar or two
congrats, in the UK I still have never found media for less the 6 for
a 25gb Disk (and I gave up even looking a while back now).  By far and
away the most cost effective way to back up your data is buy a 1TB
plus hard drive and dump the data onto it.  I run a Raid6 setup and
realised a long time back there are few, if any, effective backup
strategies that work once you start to look into the multi TB storage
range notwithstanding the storage issues it physically takes more then
24hours to back up all my library.

I do backup chunks every month or so and keep the other drives offsite
so I'll never have a totally destructive failure, however a day to day
strategy would frankly just work out either too expensive or too
labour intensive to be practicable.  RAID6 with a hot spare minimises
the risk factors and that's sufficient for me.
