I have been looking for A Way to Backup to a Hard Medium (eg DVD) Very Large Data Set >10 GB
TIA
Try Toast 9, it's backup utility can "span" several disks...
Happy Mac'ing!

I was interested in the answer as well, until I read the reviews on the Apple (Canada)
web site.
Unless you are special ordering your DVD media (i.e. high quality) I wouldn't rely on today's optical media for a good backup.
The quality is just not there. Scratches, fading, even the aluminum can flake off.
People who do use optical media for archiving special order Taiyo Yuden (not knock off) or Kodak gold-on-gold disks.
Online backup is the future. Backup that 10gb over a weekend and then after that incremental backups where only new or changed files get backed up. Check out idrive.com or spideroak .

I would not dismiss DVD recordables out of hand. See this article:
http://www.clir.org/pubs/reports/pub121/sec4.html
"Care and Handling of CDs and DVDs: A Guide for Librarians and Archivists" from the Council on Library and Information Resources.
In particular:
Quote"Among the manufacturers that have done testing, there is consensus that, under recommended storage conditions, CD-R, DVD-R, and DVD+R discs should have a life expectancy of 100 to 200 years or more; CD-RW, DVD-RW, DVD+RW, and DVD-RAM discs should have a life expectancy of 25 years or more. "
That article was written in 2003. If you have CD-R media from that time you were paying at least $3 each. DVDs would have been upwards of $10. If you have media from that time then I agree with the longevity arguement as it applies to those disks.
However things being made now are cheap, cheap, cheap. The dye layer is as thin as possible and so is the aluminum. I really don't think the article applies to the stuff being pumped out of China now.
Unless you are special ordering your disks. See:
http://www.ncix.com/products/index.php?sku=26622&vpn=51101&manufacture=Kodak
Use these and it's all good. But consider the long term. Cds and dvds will start to pile up. You will also not be protected against fire or theft.
Best regards,
Ed

Your comment is appreciated, but we don't know what you mean - what answer? Reviews of what? Can you leave an URL?
Happy Mac'ing,
