rsync should work well, though as Dave noted you need enough disk
space on the destination machine to hold a second temporary copy
Memory usage should be moderate. If not, report a bug.
If you're feeling adventurous, you might like to investigate the rdiff
tool available from rproxy.samba.org. This might give you a reduction
in the amount of disk IO compared to rsync, depending on the load.
