How to backup file and directory using "Rsync"

Backup Local host to Remote host 

First time, rsync replicates the whole content between the source and destination directories. Next time, rsync transfers only the changed blocks or bytes to the destination location

   [root@server ~]#   rsync   -avzr   /Datas   manivel@192.168.0.123:/home/manivel/

-z --> to enable compression
-r --> recursive
-v --> verbose
-a --> Preserves permissions, timestamp and symbolic links.

Backup Remote host to Local host
