RSync is useful for fast incremental transfer of data. It is very popular across business organizations as it comes with some pretty handy features which sets it apart from the rest. Some of them are;
1) Security – One can transmit the data using the ssh tunneling which provides encryption & safety from eavesdroppers.
2) Speed – Since rsync transmits only the data which has changed over subsequent time, the transmission is fast as only the bits which are changed are transferred & not the entire file. This can mean tremendous saving of time. It also comes with options which lets you fine-tune the transfer which can further improve the transfer speed.
3) Less Bandwidth Intensive – Rsync uses compression & decompression algorithms at the sending & receiving end respectively. This not only speeds up the transfer but also saves the bandwidth.
