That's only true if you use RAID, when there is a good copy to use. If
you have a single disk, they can only let you know a file is corrupt but
not restore it.
I run ext4, over lvm, over raid, over dm-integrity, over spinning rust.
Quite a lot ... dm-integrity in particular is (of necessity) lashed up a
bit. But lvm over raid is normal.

In particular, as a matter of course, I snapshot my root partition using
lvm before I "emerge --update", though I've never had any trouble that
warrants trying to recover. It'll be quite a shock if I do ...
