Does anyone use it for family photo backup for generation to pass on? I am struggling to come up with a good back up solution that last ages.
I debated doing this recently but ultimately spent a lot of money on an LTO-6 tape drive instead, just due to the cost efficiency over time for larger amounts of data. I justified it to myself as I needed to either expand my NAS or clear stuff off it, and the drive was the same price as buying two new HDDs to expand the NAS thanks to the obscene price inflation at the moment. As I’d likely need to further expand my NAS next year (I’m shooting a lot of photo and video) I think this works out a much more cost effective way of storing this data long term when I likely don’t need to access it much.
Are Verbatim's M-Disc Blu-Rays still really M-Disc? There was something about how they changed the recipe a few years ago, and the counter-argument was that Blu-Ray discs are non-organic anyway, which was the main feature of M-Disc DVD.
There's very few companies now making new Blu-Ray drives too. Pioneer has supposedly stopped producing them, and the ASUS drive I bought earlier this year was one of the only SKUs on the market. Sony stopped producing high-capacity recordable BDXL discs too which means they aren't much of an option now for large backups.
This seems a little over the top to me.
Just use a magnetic hard disk and your data will be fine for many decades if not centuries. You don't need M-Blu Rays (which have very limited capacity anyway). A hard disk is cheap and stores several Terabytes.
You obviously need to store the data in a physically remote place like your shed, car or safe deposit box in case your house burns down.
Never, ever use a SSD if you want your data to be safe for any amount of time. What's worse, SSDs can fail unexpectedly with almost zero chance of data recovery.
Hard drives are way bigger, but M-Disk is more reliable for very long term storage.
I use a 2.5" drive. I find them ideal. But then again my backup footprint isn't double-digit terabytes.
With the decline in quality I am no longer confident my HDDs are actually a save backup strategy.
I have so many photos of vacations and people who I've buried over the years, that I don't want to lose.
So I was thinking about using Blu-ray M-Disks as well, these last couple of months.
Now that I'm at ~$350 a year on Backblaze I need to look at this again. Or the LTO-6 tapes.
100% everything here. That level of tamper evidence should be good enough for the reasonable individual, IMHO.
On the enterprise scale, the question I think everyone should be asking is: Do they have LTO tapes on a shelf? Fundamentally the same issue (but larger), in terms of needing to ensure it's physically separate, and secure, and tamper evident. =)
Anything in the cloud or connected to your network can be hacked. The backup of last resort must be on a shelf.
