Not a lot of folks can justify paying a premium for a Blu-ray burner and then the media to go along with it. At the other end of the pricing spectrum, DVD burners and media are dirt cheap, and so are mechanical hard drives, for that matter. But if you are going to spend a portion of your fun money on Blu-ray backups, it certainly helps if you can write to discs more than once, something you'll be able to do with Panasonic's upcoming 100GB rewritable Blu-ray disc.
According to TechOn, Panasonic's Digital AVC Marketing Division is gearing up to release a rewritable single-sided three-layer Blu-ray disc with 100GB of capacity on April 15, 2011. Panasonic says it's the world's first 100GB Blu-ray disc than can be written to more than once.
The new disc supports 2x speed writes and is compatible with BDXL Part1 Version3. And at 100GB, it's twice as large as existing single-sided two-layer Blu-ray discs. Panasonic says you'll be able to archive 12 hours of a terrestrial digital TV program in the DR mode (with a transfer rate of 17Mbps) and about eight hours and 40 minutes of a BS digital TV program in the DR mode (transfer rate of 24Mbps).
No word yet on price.

For around $100 dollars you can buy an external HD 1 terabyte I can store a lot of backup on that. I own 3 of them and will never go with BD burners

I picked up a blu-ray burner when they were fairly new, i also picked up a stack of the 50gb DL RW discs to go with it.
it is very convienient to use it for storing long term backups of iso images and even pc backups. all in all they are a great deal, plus im able to rip BD movies in full quality.
if these discs come out it would be great, a full system image with key apps etc... installed hits about 60-80gb these will be perfect for a one disc image solution.
also great for long term archive/storage of data off site with little chance of damage or corruption. but like all good backups you should have mkore than one and test them.

Quote " with little chance of damage or corruption " whatta hell are you talking about !!!! No one knows how long BD discs last before data gets corrupted . I personally agree with most commenters it's cheaper and more safer to use external hard drives.

may be cheaper per GB for storage. but i would not use an external drive as any primary backup, they are to prone to physical or enviromental damage as compared to cd/dvd/bd.
plus, when storing any type of backup medium off site, non mechanical is best as it is less likely to be damaged in shipment. a cd/dvd/bd is smaller and lighter as well. when storing massive quantaties of data, it is always best to split that data accros multiple drives, discs, tapes etc... in a way that you can recover from each unit individually, so if one fails the entire collection is not lost.
and from this FAQ below, 30-50 years will outlast most drives or there technology.

How long will a Blu-ray disc last? Answer:
BD-RE can be written up to 1000 times. Blu-ray discs should last anywhere from 30 to 50 years.

But are you still going to need those drive images, mp3s, data, and game backups, from 50 years ago? Surely not. Newer programs, operating systems, and music formats will have replaced what you have now long before 50 yrs shows up.

How long does it take to burn 100GB of data at 2x speed? Certainly not faster than copying 100GB of data to a SSD drive. My fun money will be going towards an overpriced slc SSD drive.

With external/internal HD prices dropping like a rock that you can use for storage, I'm not exactly sure what the point of these expensive burnable blu-rays discs are.
