Nothing wrong with building your own version, but you'll want to disable
profiling in most cases (the profiling code will noticeably hurt
performance). The files in the gprof subdirectory are produced by the
profiler.
The error message you see (Stale file handle) suggests that you are
using an NFS-mounted filesystem and that someone may have deleted a
directory while you were running the backup. That may be ok, but I
personally would not trust a backup that reported an error (especially
if you can't explain the error, which I can't).
