Backups only do so much? Could you elaborate on what your backups don't do?

My backups allow me to recover from theft, hardware failure, accidental deletion, and more. If my computer were to burst into flames right now, I would only lose 30 minutes of work.

Even if SSDs reliably went read-only at the end of their service life, I would still keep my existing backup strategy. There are so many ways to lose data without disk failure.

I have a laptop, and as such tend to use it on-the-go.

As such, backups won't capture anything after the last time I had access to my backup volume.

Also, again, I don't always have access to my backup volume.

I'm not saying "I wish that they would go read-only so I didn't have to back up" - I am perfectly well aware of the need to back things up.

Backups don't keep your system somewhat running in the event of failure. And unless you run a full image backup, it takes much more time and effort to restore from a data-only backup than to simply do a direct copy off of a write-locked but perfectly readable drive.
