Got one.
I have 935Gb of data (soon to be 1.2Tb)
Each DVD holds 4.7Gb and takes 20-30 mins to burn.
Any other ideas ? ;)

PS Seriously - the data is films, my CDs, DVDs, TV shows and the like. 
It's a bummer to lose but in the grand scheme of things it's only the telly.
My _real_ personal data (photos etc) are mirrored onto physically 
seperate disks each night. The 'backups' are remounted read-only. It's 
the 'rsync snapshot' method.

See: http://www.mikerubel.org/computers/rsync_snapshots/

Thanks for your concern though :)
