Neither format is sufficient for Enterprise storage. While many laud Blu-ray's 40Mbps data rate for video this is absolutely abysmal performance for backup storage which needs more like 40MBps.
Optical is declining as a archival storage medium. HP hacked their UDO lineup and most companies are moving to a nearline/offline strategy which incorporates a backing up to disc and then archiving to tape or utilizing a Virtual Tape Library (VTL) which emulates various tape products.
Tape doesn't sound sexy but you can't argue with the 800GB of storage and 576GB specs of a StorageWorks Ultrium 960 drive. The roadmap looks good here too with Ultrium 4 jumping up to 1.6TB of data and faster speeds.
Optical has always had promise but the performance never matched existing technologies. I'm sure someone will bring up the 300GB Holographic vaporware but that's substandard by today's standard in archival tech. I'm tired of waiting for optical promises.
My own home backup system will consist of Time Machine snapshots from OS X Leaopard to an external hard drive. Instant user restore and the ability to do off site backup are better than nothing and I get this for the price of an OS upgrade and storage...a win/win.
