Yes, but it still goes through the motions of 'reading' what could
potentially be many TB of data even from a small file with the
filesystem delivering all those nulls. It has been a long time since
I had that problem but it did in fact cause trouble at least with the
rsync back then and slower CPUs. It could be that rsync tried to
write them all at the other end too.
