==Cloud-based Synchronization of Distributed File System==

More and more users have multiple devices with ad hoc connectivity. These devices need to be synchronized. In fact, an important point is to maintain user data by synchronizing replicated data sets between an arbitrary number of servers. This is useful for the backups and also for offline operation. Indeed, when the user network conditions are not good, then the user device will selectively replicate a part of data that will be modified later and off-line. Once the network conditions become good, it makes the synchronization .<ref> {{harvnb|Sandesh Uppoor, Michail D. Flouris, and Angelos Bilas|p=1|id=Uppoor}}</ref>.

Two approaches exists to tackle with the distributed synchronization issue: the user-controlled peer-to-peer synchronization and the cloud master-replica synchronization approach. <ref> {{harvnb|Sandesh Uppoor, Michail D. Flouris, and Angelos Bilas|p=1|id=Uppoor}}</ref>.

* user-controlled peer-to-peer: software such as [[w:rsync|rsync]] must be installed in all users computers that contain their data. The files are synchronized by a peer-to-peer synchronization in a way that users has to give all the network addresses of the devices and the synchronization parameters and thus made a manual process.
