--rsh=COMMAND, -e
              This option allows you to choose an alternative remote shell program to use for communication between the local and remote  copies  of  rsync. Typically, rsync is configured to use ssh by default, but you may prefer to use rsh on a local network.

--archive, -a
              This is equivalent to `-rlptgoD`.
			  It is a quick way of saying you want recursion and want to preserve almost everything.  
			  Be aware that it does not include preserving ACLs (-A), xattrs (-X), atimes (-U), crtimes (-N), nor the finding and preserving of hardlinks (-H).
			  
 --dry-run, -n
              This  makes  rsync perform a trial run that doesn't make any changes (and produces mostly the same output as a real run).  It is most commonly used in combination with the --verbose, -v and/or --itemize-changes, -i options to see what an rsync command is going to do before one actually runs it.

 --delete
              This  tells rsync to delete extraneous files from the receiving side (ones that aren't on the sending side), but only for the directories that are being synchronized.
              
 --compress, -z
              With this option, rsync compresses the file data as it is sent to the destination machine, which reduces the amount of data being transmitted

   --cvs-exclude, -C
		  This is a useful shorthand for excluding a broad range of files that you often don't want to transfer between systems. 

--chown=USER:GROUP
              This option forces all files to be owned by USER with group GROUP.
