How would you backup 1TB of data in a server with 4x 250GB drives all

One terabyte divided by 8 gigabytes per double-layer DVD comes out to 125
DVDs per backup.
Are you out of your freaking mind?
If a dual layer takes 10 minutes to burn (just a guess, don't own
one) including time to prep the next one, it would take you 1250
minutes, or just over 20 hours of continuous burning. That doesn't
factor in the time to chunk up your drive accordingly. So you'd
have to be offline for at least 2 days. Your dual layers would cost
you about $125. A 1TB external drive starts at around $300. Is it
worth all that time & effort to try and save $175?
also, do you really need to back up all 1TB? i guess if it really is
pure "data", then, yes.

Ok, the server is 1TB but actually only 50GB of personal pictures need
to be backed up. And I need a solution that burns to multiple dvds.
No tapes and no hard drives.
