->> Searching the message board archive for "blu-ray" shows it's been a while since this was brought up. So:
Who's using Blu-Ray in their archiving system? Recommendations on burners? Recommendations on good sources for BR discs?
I like having a disc-based backup in addition to hard drives & online, but with DSLR video now, I'm going through DVDs faster than ever. |

->> Optical disks like Blue-Ray are not a viable archiving solution. Either the disk will either mechanically or chemically fall apart within any reasonable time period. Lots and lots of research has been done on this topic and there is no save and forget way to archive digital files. Either the media is chemically/physically short lived or the technology around it is. The best current way to archive digital files is on mirrored hard drives that are stored apart from each other for physical safety. Once a new technology replaces the drives that you used you have no choice but to buy the new kind of drives and transfer everything to the new drive type.
In a few years reading data on an EIDE drive will be tough as we are already mostly using SATA drives and SDD is starting to take hold and that will certainly bring an different interface as well.
However given that drives are so cheap right now you are spending more money and time backing your images up on optical disks than onto hard drives. Get a removable hard drive bay and archive to discs from there.
Oh and RAID isn't an archive, it's an on site data protection system so don't think that a DROBO will save you either. |

| ->> I 2nd Jon's post. It's so inexpensive to mirror drives these days. WD, 1TB internal hard drives are $99 each. I cant inagine how much blu-ray discs and the burner would cost... |

->> Yep - using something like Thermaltake's BlacX (http://www.thermaltakeusa.com/Products.aspx?C=1346) helps me to swap out drives quickly and easily.
And in the voice of my former journalism prof, "50 points off for factual error." It's Blu-ray, not Blu-Ray or Blue-Ray. |

->> one question then maybe...
Do Blu-ray discs degrade any faster than traditional DVDs?
I'm just asking in general as I understand it will differ by brand/maker. |

->> I dont think any disc-based item: CD, DVD, or Blu-ray are dependable longer than 3-4 years? For me, I have pulled info off CD's burned in 2003 but then again, I have have CD's from the same year fail on my PC with a "redundancy error"...unreadable basically.
The best bet is to mirror drives and upgrade as the latest, greatest technology comes around.
I too use the Thermaltake BlacX's. They are great for backing up images and store very easily in the gun safe... |

->> In theory Blu-ray should have a much much longer life span than regular DVD's if they are properly cared for (I've read 30-150 years).
DVD's use a photosensitive organic dye to record on while Blu-Ray's recording material is bonded silicon and copper. This make the Blu-Ray less prone to degrading.
Heres some info on BD-RE discs and the life of them

->> It is best to follow a back up strategy following the 3-2-1 rule(and it sounds like you are). At least three copies, 2 media types and one copy off site or offline. As Johnathan said there is no way to archive and forget digital data. All back up copies should be verified routinely.
Having said that, I do have a client who is using Blu-ray(La Cie external) as her second media for backup. With its lager storage size, I think it is a much more practical option than multiple DVDs. It is interesting to read that they might also be more archival. Although the prices for media are still high, they are coming down. I hope to buy one in the near future.

| ->> I am a big fan of DROBO. YOu can buy drives of any size and make and double back up other drives, or get yet another DROBO! I haver felt more secure in my data storage. My DVDs now make nice coasters on my coffee tables. |

->> Thanks-it has been a while since I have really taken a hard look at my storage strategery.
I am going to move to a Drobo for primary storage and access and hard drives as backups #2 and 3. Hadn't really priced drives in a while and the price per gigabyte simply can't be beat.
One last question for those using 3.5" SATA drives in an external enclosure--how do you store the drives? Their critical parts seem a little too exposed when they're not in their enclosures. |
