Backing up a damaged SSD

I've got a laptop with a damaged main drive. It's a 2TB NVME SSD, and gets
an error on a dd copy of the main Ubuntu partition, and about 200 errors on
a ntfsclone --rescue of my Windows partition.

Of course, I'm getting it replaced -- it's even under warranty from the
company that makes the laptop. But I'd like to have the best backup
possible. I like the ntfsclone --rescue option. I wonder if the dd
--ignore-failed-read works the same way -- skip a single sector, on both
the input and the output or whether is skips a whole block of the size I
told it to use. I also wonder if there's anything better.
