dd_rescue helps when nothing else can: your disk has crashed and you
try to copy it over to another one. While standard Unix tools like cp,
cat, and dd will "abort" on every I/O error, dd_rescue does not.
dd_rescue has many other goodies; optimization by using large blocks
as long as no errors are in sight and falling back to small ones; reverse
direction copy; splice in-kernel zerocopy; O_DIRECT support; preallocation
with fallocate(); random number writing etc.
There is no official package available for openSUSE Leap 16.0
