As Sony exits, Verbatim doubles down on optical media — stable supply of discs is a "top priority" despite shrinking market
As Sony exits, Verbatim doubles down on optical media — stable supply of discs is a "top priority" despite shrinking market
You're viewing a single thread.
M-Disc/Archive Blue ray discs are currently pretty much unrivaled if one needs WORM(write once read many) storage for important data.
Anything cloud is an issue in that regards, while a few options exist that somewhat imitate WORM to comply with regulations they are often expensive, harder to maintain and, if long term storage is required, prohibitivly expensive.
The next option, Tandberg RDX needs a far less popular writer, it's WORM media is far more expensive, far more sensitive towards exterior influences and it's much harder to make sure you will be able to read the data in 20 years.
LTO is nice, the tapes are somewhat cheap but the drives are extremely expensive - far to expensive for smaller businesses or consumers.
(And please for the love of god, normal exterior HDs,etc. are NOT backup media for long term storage, especially not WORM- which is important in times of ransomware attacks)
So in the end verbatim would be an absolute idiot to destroy this market. I work with a lot of smaller healthcare facilities and they all exclusively work with them - they routinely burn their data on a M-Disc that is then stored in a secure location, as they all need to provide their patient records for at least 10, mostly for 15, in some cases for 30 or more years. The doctors can literally go to jail if they do not comply with that.(And getting hacked or your building burning down is not an excuse)
As a CEO of a small company we also need to retain certain tax and accounting data for 10 years, some for 20 years. And even as a individual I have some stuff I legally must retain for 10 years.
And of course photos of important life events and some documents (insurance, mortgage) are also something I don't want to loose if the house burns down. Therefore the important stuff gets burned to a M-Disc three times a year and then locked into a bank vault quite a bit away.
What do people normally store one write one mediums I feel like I'd have a hard time working with write once items except for like maybe just music storage
Personally I store all "Very important data" on it - things I really don't want to loose even if my data storage at home and my cloud storage gets compromised. Among them:
-
Photos of life events. Wedding, photos of the kids, photos of relatives that are now deceased, etc.
-
Important documents. Birth certificates, copies of IDs, passports, insurance documents, degrees and certificates, banking/taxation/accounting documents, bills for the important stuff like major renovations, the expensive IT stuff, etc.*
-
Backup of important files (for me Uni files for my lectures, some work files, backup of the password DBs, plans for the house, a tutorial how to receive files from the cloud storage, decryption keys, etc.)
(*: This is more a theoretical choice - as I can get 100GB media for the same price as the 50GB I currently simply copy the full paperless file storage. But the script normally only copies these. They are flagged with a custom field in paperless)
I do not use addition to the storage,so no "these files are new since the last copy" but I simply make a full backup of these files every time (usually three times a year). This reduces the risk of one backup being compromised - very likely I only fall back 4 month which is tolerable. The discs itself are stored in a locked box in a bank vault a bit further away. I have to go there a few times a year anyway,so it's not hassle. (And they have great coffee). The box costs me 50€ a year and has enough room for 50 years of M Disks and a few extra items.
Anything taxation related must be stored for 10 years even by private individuals here,so there is that.
My customers (smaller health care organisations, e.g. your fellow neighbourhood dentist or GP) usually store patient data and accounting data on them. They need to store them long term (up to 30 years) for legal reasons, additionally they don't want a opposing lawyer to later tell them "you have manipulated the data". Having multiple copies that cannot be manipulated reduces that claim to "you manipulated before you stored it" and we have other ways to fight that.
Could you store a checksum of the backup with an NFT? Think I just threw up a little bit there, but perhaps there is actually a use case for them them. At least it proves the backup remains since it was created regardless of how many copies you have
This is perhaps more useful, serving as both checksum and data correction.

Not that it can fit in the blockchain though. At least from what little I know about blockchains, they can't possibly store any substantial amount of data.
In theory maybe? But...I don't know why one should.

How are external HDs not a backup? Sure if it's left attached 24/7 it would also get caught by ransomware potentially but otherwise surely that is what external media is good for?
Most of my data isn't that important, but have a script that can sync a live copy to several locations over the LAN and create a timestamped compressed folder of it, usually keep a few of the timestamped copies on external media.
External HDs are good for short term backup - I do use them for that myself.
But they are not suitable for long term backup, they are susceptible to damage, sector errors,bit rod and interference.
If you leave them unpowered for longer times the chances that the mechanical components are gonna fail are actually increased.
Some of these issues can be reduced,but never fully.
Additionally there are ransomware viruses that directly attack them - they intentionally encrypt the backups first when the drives are connected before they attack the live data. And in at least one case I know of the attackers bricked the HD firmware.
Therefore for long term storage of really important things WORM (write once read many) media is to be preferred - even if the attackers can access the disk for some reason they cannot alter the once written data.
