Hi,

I’m not sure if this is the right community for my question, but as my daily driver is Linux, it feels somewhat relevant.

I have a lot of data on my backup drives, and recently added 50GB to my already 300GB of storage (I can already hear the comments about how low/high/boring that is). It’s mostly family pictures, videos, and documents since 2004, much of which has already been compressed using self-made bash scripts (so it’s Linux-related ^^).

I have a lot of data that I don’t need regular access to and won’t be changing anymore. I’m looking for a way to archive it securely, separate from my backup but still safe.

My initial thought was to burn it onto DVDs, but that’s quite outdated and DVDs don’t hold much data. Blu-ray discs can store more, but I’m unsure about their longevity. Is there a better option? I’m looking for something immutable, safe, easy to use, and that will stand the test of time.

I read about data crystals, but they seem to be still in the research phase and not available for consumers. What about using old hard drives? Don’t they need to be powered on every few months/years to maintain the magnetic charges?

What do you think? How do you archive data that won’t change and doesn’t need to be very accessible?

Cheers

    Someone else has mentioned M-Disc and I want to second that. The benefit of using a storage format like this is that the actual storage media is designed to last a long time, and it is separate from the drive mechanism. This is a very important feature - the data is safe from mechanical, electrical and electronic failure because the storage is independent of the drive. If your drive dies, you can replace it with no risk to the data. Every serious form of archival data storage is the same - the storage media is separate from the reading device.

    An M-Disc drive is required to write data, but any DVD or BD drive can read the data. It should be possible to acquire a replacement DVD drive to recover the data from secondary markets (eBay) for a very long time if necessary, even after they’re no longer manufactured.

      M-disk, never heard of that. I got a quick research done and it seems to be exactly what I was looking for. Thank you!
