Rsync will only move files. You also need to move the
bootloader. Also rsync will be less efficient than just
copying the files. Rsync is good for updating the copy at
the last minute if needed.
It is a bit difficult but you will still need to identify
the files affected.
If it is just a few bad sectors and not the drive dying you
might just want to force the drive to remap the bad sectors.
That is done by writing to them. There are a couple of ways
of doing that.
