Should I blame rsync (or the way I use it)?

Next, I will do a plain 'cp -a' between the original source (sdh on
/sata) and target(md127 on /data1) to see how it goes.

If you say how you use it, someone might be able to answer that. Give
the exact command line with all options (e.g. if you have strict change
detection you might be checksumming every file on the source before
deciding to copy it).

First, I already did this test and it still chokes after a few GB. The problem is still there
and it is not only an rsync problem. But why does rsync use 100% CPU?

I thought that I gave the command but I did not initially, yet when I show the output of 'ps' it says:
	sudo rsync -aHSK --stats --progress --checksum-choice=none --no-compress -W /sata/backups/tapes /data1/no-backup/old-backups/
so there it is.
