I found this report from NIST that estimates tape to last 20 years, CD-R and DVD-R 30 years, and M-DISC 100 years 🤷 (I didn’t even know optical was used professionally, and found the term “optical jukebox” to be hilarious :)
But more importantly, an actively maintained storage system will last forever (as long as maintained). And for example AWS S3 Glacier Deep Archive costs just $0.00099 / GB / month*, so you can store terabytes for the price of a cup of coffee.
*Plus extra fees for access and stuff, but the point is managed storage isn’t particularly expensive unless you have very large amounts of data or heavy usage.
