How long did it used to take, and what changed?

It's progressively gotten worse as the amount of data has grown, over the past year or two.

However, what I'm seeing now is that everything else on the system basically hangs until the copy operation is done. For example an unrelated database server and web server (locally) just freezes  when a cp request executes from the rsnapshot cron.

It has always had some slow down, but usually only a few seconds....30 at the most. Now it is over 4 minutes until I can type at the shell again.
