There are some interesting regulations in finance, I know at least one bank that keeps offline backups on tapes, but wonder how often do they test it.
My experience with them tells me, they are not the most tech savvy bunch. If they ever need to use backups with the software they were provided decades ago / by modern fast failing agile company (according to taste), even if they can get the source it will be very hard to compile and run them. Reproducible builds is not exactly a solved problem.
they need to put their entire environment into docker container and archive the images! theyll be able to recreate their whole environment at any time in the future!
