Examples on how to use Rsync for local and remote data backups and synchonizations

Rsync is a very useful tool which allows Linux system administrators synchronize data locally or with a remote filesystem via the ssh protocol or by using the rsync daemon. Using rsync is more convenient than simply copying data, because it is able to spot and synchronize only the differences between a source and a destination. The program has options to preserve standard and extended filesystem permissions, compress the data during transfers and more. We will see the most used ones in this guide.
