  The issue of repairing Reed-Solomon codes currently employed in industry has
been sporadically discussed in the literature. In this work we carry out a
systematic study of these codes and investigate important aspects of repairing
them under the trace repair framework, including which evaluation points to
select and how to implement a trace repair scheme efficiently. In particular,
we employ different heuristic algorithms to search for low-bandwidth repair
schemes for codes of short lengths with typical redundancies and establish
three tables of current best repair schemes for $[n, k]$ Reed-Solomon codes
over GF(256) with $4 \leq n \leq 16$ and $r = n - k \in \{2,3,4\}$. The tables
cover most known codes currently used in the distributed storage industry.
