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.
I’ve done this. I don’t remember the retailer but they let me RMA it when I told them their website had recommended the particular SSD and external enclosure combo being bought together but they wouldn’t fit together without first removing that part.
I will never attempt to do this again. Fucking stupid.
