This type of question is asked semi-frequently and the answers tend to be around physical preservation.
So here's a thought. Why not build a "Computational Knowledge Bootloader" that contained enough information to build a sequence of computational devices of increasing complexity starting with the absolute basics of math and language.
If we had that, then all of these types of questions of digital preservation could be answered with something like "Go to the website and upload your information into a Tier 20 CKB device. Enter your shipping address and payment information. A collection of etched titanium plates will arrive in 3-4 weeks. Put them in a safe."
500 years later, decoding might look like finding or building up to a Tier 20 CKB device and scanning the plates. If the instructions were standardized, there should be lots of lower tier devices scattered around.
