method for copy (only "cp" currently supported). Alpha support for
"scp" was added in November 2000. Your experience with the scp method
will vary with your ability to understand how scp works. 'man scp'
and 'man ssh' are your friends.
The destination directory _must exist_ on the target machine using
the scp method. Liberal use of the --debug option will help you figure
out what's really going on when you do an scp.
Note that using scp will lock your tables for a _long_ time unless
your network connection is _fast_. If this is unacceptable to you,
use the 'cp' method to copy the tables to some temporary area and then
scp or rsync the files at your leisure.
