I’m no tech geek, but shouldn’t the back up system have been a copy of the original program, kept in case there was a problem with the update, so they could revert back to the original? How could there have been a corrupted file in the backup then?

The corrupted part of the file wasn't needed immediately, so it got backed up. I once had a system crash because the original programmer had used a seven character date field. It blew up on October 10th.

I had y2k issues with microsoft cbasic and the year digit singles rolling from 9 to 0 and the carry in the tens went from 9 to : The next ascii character
