FTP Vs. Rsync?

By | September 27, 2011

Rsync is a great utility to manage downloads of transformation of Linux hosting servers and it is very easy to set up on a web hosting server. After technically studying it one comes to know that it copies only diffs of files which have been actually changed and compressed, through SSH. And this copying process is conducted without any scripted FTP session or any other format of file transfer script.

Following are a few concepts explained which are involved in ‘Rsync’ operations.
Diffs – Not the whole file, but only the changed portion of those files are transferred. This selective transformation makes the speed of update process faster. Unlike ‘Diffs’ FTP transfers the entire file though the change is very tiny.
Compression – The transferred small portions (Diffs) of the files are compressed while the transformation process is going on and this reduces the time required for transferring the Diffs. This also reduces the load on networks used for transformation.
SSH Encryption – With ‘Rsync’ security is provided on (a) higher level than the FTP because the stream from ‘Rsync’ is passed through the ssh protocol which encrypts your session and not the RSH.
Rsync can not be used with a windows web hosting server so one should approach other suitable utilities like ‘Robocopy’ or ‘Richcopy’.
