#Welcome to Nehra Classes Youtube Channel#
#Automate Backup Using rsync & crontab in Linux#
============================================
rsync or remote synchronization is a software utility for Unix-Like systems that efficiently sync files and directories between two hosts or machines.
One of them being the source or the local-host from which the files will be synced, the other one being the remote-host, on which synchronization will take place.

There are basically two ways in which rsync can copy/sync data:
Copying/syncing to/from another host over any remote shell like ssh, rsh.
Copying/Syncing through rsync daemon using TCP.
