I saw on Reddit a post about the CDC in the US deleting the data about long covid. (I have long covid myself).

In bioscience and medicine, there are very strict rules against local copies. Even having data in the RAM (like loading data locally to compute stats) is forbidden. Saving precious data is sometimes an act of civil disobedience - I luckily don't have these constrain. Although I'm based in Canada, I'm backing up everything in case this insanity is going to cross the border
