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 http://adterrasperaspera.com/blog/2006/10/30/how-to-choose-cddvd-archival-media 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. -- Lamar Owen www.pari.edu -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
