	$ tar -c -C /from/ -f - | ssh host tar -x -C /to/ -f -

where compression arguments e.g. -J are advisable if over a WAN, "ssh 
host" is optional, and -v really slows things down, especially if used 
on both sides or over a WAN.

For Cygwin, --exclude /cygdrive, /dev, /proc, /tmp, /var/log and maybe 
some others, so better to add to an --exclude-from FILE:

	$ info tar exclude

and don't forget exclusions must omit /from/ and /to/ paths but may 
include shell wildcard patterns "*", "?", "[...]", "[!...]", and 
[?*+@!](...|...) if shopt extglob enabled:

	$ info bash pattern
