But on another level, I guess if hardware fails, then well, you buy more hardware, which is good for Apple. Presumably people who bought in the past from Apple won't turn around and buy an Acer or HP laptop. They'll still buy Apple.
It would be much nicer if your computer said, “I've detected a bit flip, please restore this file from backup”
I'll go further and say that even backup that forward-propagates corruption is not backup either - all the incremental backups from the moment of corruption are worthless. Bottomline: if your backup cannot be restored with integrity intact - it's not backup!

Yes. So 30 days after your file was corrupted, you will only have corrupted copies left.
