The Approach of Base Concept of System
System definition can be seen of two approach, which is procedure approach and component / element approach
- Procedure Approach
System is a job network of interrelates procedure, flock together to do anactivity or to solve a given target (Taken from fundamental of system analysis)
– Definition of Procedure is a medley in point of instruction step that enlightens (what) one that has to be worked, (who) one that works, (when) worked and (how) working it
- Element Approach
System is interacted a group of elements to achieve a certain goal.

Untuk apa rsync?
Rsync adalah tool untuk transfer dan sinkronisasi file atau tree (struktur direktori dan file) secara satu arah, baik transfer lokal (di sistem yang sama) maupun remote (jaringan/internet). Fungsi rsync mirip/identik dengan tool-tool ini: cp, mv, scp, FTP client. Rsync biasanya digabungkan dengan SSH sebagai metode transpor remotenya, walaupun dapat juga disetup untuk menjadi daemon sehingga tidak membutuhkan SSH. Dalam kasus-kasus tertentu rsync juga dapat digunakan menggantikan HTTP client (seperti wget).
