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My initial thought was to burn it onto DVDs, but that’s quite outdated and DVDs don’t hold much data.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

    Assume anything you can buy has a shelf life and set a yearly reminder on your calendar to copy forward stuff more than five or so years old, if those files are of significant value to you. Or for the documents, print them out—paper has better longevity than any consumer-available electronic storage.

    That being said, quality optical discs are probably the best option in terms of price to longevity ratio for the average person right now. Just keep in mind that they are not guaranteed to last forever and do need to be recopied from time to time.

    (I have yet to have a DVD fail on me, but I keep them in hard plastic jewel cases in climate-controlled conditions, and I’ve probably just been lucky.)
