Input/output error (5) usually indicates some hardware problem, not
related to the application.

As it's just a single file you're trying to copy, why not use cp?
Although I expect that cp will also throw an IO error at some point.

You could use --inplace --append --partial with rsync and repeat the
command until it finally completes.
