well its actually coping all files again as i check the dates of all files they are with the last cronjob run time.

plus the group is not being moved with the files, its using the user primary group not the 2nd group he belongs to.

i think am having a problem with the flags or something?

Do you mean that it is reading every file or that it is
actually copying them?  It could be the fault of the NFS
server or the client.  Many people use rsync on NFS mounted
dirs without problems.  It is better to run on local dirs
but some NFS servers don't have the resources to support
rsync.  If you must rsync on a NFS mount use the
--whole-file option.
