Anyone writing images to Blu-ray discs as part of you backup strategy? If so, which size disc?
I currently backup to multiple external hard drives. Previously, before 25+MB RAW images, I also burned images to DVD. A couple years ago I started burning to 25 GB Blu-ray, but I've fallen behind. I've also had write issues with some discs failing. Grouping images to fit 25 GB discs can also be a pain. It's now cheaper and easier to get another external drive, like the WD My Passport to use as a backup. But, will a hard drive only strategy be reliable in the long run?
There is something about write-once media without moving parts (like Blu-ray discs) that intuitively seems to be more reliable for long-term storage than moving-platter-based media. But, I've had issues with burning discs on one drive that can't be read on another (even after finalizing them). This leaves me with the fear that I could burn a bunch of discs on a drive that might drift out alignment only to find out years later that I can't read them.
I would like to incorporate the cloud, but last year (2014), I accumulated over 33,000 RAW images that consume roughly 950 GB. A TB/year can of data on the cloud can get expensive quick.
Backblaze is $50/year if you pay for the full year at once. Unlimited backup of any drive except NAS. Does not require Java which is a great thing for computer security.
