As an atheist, I ask for prayers that the backup's good.
E: Your solidarity has worked. The backup is good and not too old. Note for myself and you - install your OS on a snapshotting filesystem so that live backups are possible.
LMAO, this SSD was purchased many years ago and was in active use. The previous ASRock board it was used in had the same toolless M2 mechanism but did not have a backplate which made the bottom heatsink easily removable, which I had done and this exact SSD was installed in it. The new board's product page doesn't say anything about a backplate blocking M2 heatsink removal, or a backplate at all. Given the information available I bought the right product.
Now kindly fuck off.
