Suggestions? Copy huge directories has never been a problem for me as long as space is available. I routinely copy between two NAS servers (old/current and 2BE) and there it can be several million files and >2TB of data to copy. This works fine both for the initial copy and subsequent refresh/updates, no problem there. Now this is done under Centos6/7 on servers with 16/32GB of memory so if you try something similar on a 512MB system you might have an issue. One thing that causes hangs for me (and been an itch for a long time) is when I copy a something and the destination runs out of space. Then it just hangs and easiest fix is to kill it on both sides, fix space on destination and start over. /ps
