I work for an engineering firm. We generate a log of documentstion and have everything on our internal server. The data is on an unraid server with parity with offsite backs to two sepearate servers with raid.
However, we have designs, code and documentation which we sign of and flash to systems. These systems may never be seen again but also have a life time of 30 to 50 years for which we should provide support or build more.
Currently, we burn the data to a set of BluRays, depending on the size with redundancy and checksums, often allowing us to lose 1 of 3 discs due to damage, theft or whatever. And we will still be able to resilver and get all data from the remaining 2 discs.
I have recently seen that Bluray production is stopping.
What are other alternatives for us to use? We cannot store air gapped SSDs as not touching them for 30 years my result in data loss. HDDs are better, but I have heard running an HDD for a very long time and then stopping and storing it for many years and spinning it up again may also result in loss.
What medium can we use to solve this problem? This information may be confidential and protected by arms control and may not be backed up to other cloud services.
