[ale] rsync comparisons

[scott]

rsync compares on a file level BUT it compares timedate stamps/sizes
in "quick mode" (which is default).  but if you want it to compare
file to file, use "-c or --checksum" option.  Now this puts a heavier
load on both systems, since it does a MD5 checksum on every file that
has the same timedate stamp/size on both sides of the sync.  Now if
you want to force the copy of the whole file instead of the changed
blocks, use the --whole-file option with it.

I would use this ( -c & --whole-file) sparingly.  It is going to slow
down the copies, put heavier loads on both ends and transfer more data
(control data) back and forth.  I dont know your situation so I cant
say to use it or or not.
