I've used optical worm drives for archiving - supposedly able to outlast me (not that hard sone days) IF the kit still works....
What media does one use for offline backups?
Previously our auditors OK'd mag tape but rapid changes in format / tape capacity caused many issues reading the data and it was a planned duplication process to extend their life.
At home I have data 20+ years old on magnetic media - this has been 'refreshed' by copying from drive to drive with a byte level compare (not just checksum) - not sure why I've still got these but that's a different discussion Image may be NSFW.
Clik here to view.
The BBC have an interesting article https://www.bbc.com/future/article/2022 ... 1000-years and of course they had fun after 25 years https://www.bbc.co.uk/news/technology-13367398 and https://www.bbc.co.uk/blogs/domesday
In all cases it comes down to:
1) Is the media stable?
2) Do you have equipment that can read the media?
3) Do you have documentation of the data format?
4) Can you actually process the data if you no longer have the original hardware / OS / application?
5) Is the data worth the effort?
