Crash when copying large files

Hello Chuck!

They are approximately between 1 and 4 GB.

Thanks for the suggestions, I'll try rsync. The initial idea I had was  
copy most of the files (which are fairly static) over with tar, which  
takes ca 1.5 hours, and then run rsync to catch these changes that had  
happened during that 1.5h period. I may as well just use rsync for the  
entire process.

Past experience on other FreeBSD systems has taught me to avoid  
dump/restore for large filesystems, because it seems to be an order of  
magnitude slower than tar.
