Aw, you're too kind.

The original question could have been for a one-shot operation.  Also breaking 
the ambiguity a little, if you use DVD+R's, the data stability is 
substantially greater over time, since the mechanism for DVD+R recording is 
different from DVD-R recording.  See

At the 1TB level with 125DVD's (and, yes, a consumer grade DVD burner can do 
that; we have run duplicates of DVD's of a locally produced video segment one 
right after another for two 100-DVD+R spindles; LiteOn brand drive over a 
period of three days) it is impractical.  The OP further explained himself 
that he really only wanted to backup 50GB of that.  At the 50GB level for a 
possible one-shot backup, possibly practical, as 12 data DVD's in a modern 
drive wouldn't take too long.  Do two while you're at it.
