Re: do I always have to use either --checksum or --times ?

You should almost never use --checksum.  It is slower than just 
re-copying everything.  You should almost always use --times (or 
--archive which includes --times).  Without this rsync is almost as dumb 
as cp.  Also, ssh has been the default --ssh for a long time.
