For those who wishes to use a GUI instead of the rsync command line, you will be glad to use the Rsync GUI utility - Grsync
It is neat and give you rysnc options in GUI. The only issue is that it is quite difficuly to schedule a job using Grsync.
To install on CentOS or Fedora
# yum install grsync
To install on Linux Mint,
# apt-get install grsync
