Mac Bible and famous black page

Sorry, just a curiosity.
Does anybody remember The Mac Bible (not sure if this is the correct title) back in the days of yore,
and the famous black page with the warning to back up because one day your darling is going to crash?

And God said, “Let one be offsite.”

No. I think I had The Mac Bible too. Don’t recall it but it certainly is the truth. Thank God for the Cloud. I have my photos backed up but need the rest of it done.
