A Comparison Study for File Synchronisation

AbstractTechnology has become an integral part of our life. Education with technology is a powerful combination which can revolutionize our society. And with the Aakash tablet slated to be in the hands of every Indian student, new avenues have opened. To provide better solution for transferring files from tablet devices to institutional hubs and vice-versa file synchronization is the only solution in these days. When there are small changes between remote devices transferring files as a whole will take more time and also will cause overhead and will cause traffic in the network. The amount of data stored on the remote device will increase drastically after such type of file synchronization if the contents are audio, video and image files. To solve this problem we are focusing on some solutions, when there are some little changes between the files of the two devices. The solution has subsequently transferred updates and reconstructing files in the remote device to avoid all the above type of problems. This problem is previously tackled by using Rsync. But it is not more scalable in terms of network size and bandwidth usage. The main problem is to synchronizea large set of media files between institutional hubs, also between institutional hubs and student hand held devices. The ultimate goal of this project is to synchronize students filled with teachers PC and vice-versa. In this survey the author has studied and gone through some experimental studies for file synchronization between PCs and handheld devices
