ABSTRACT
An increased use of mobile devices such as smart phones, PDAs and tablet computers with capabilities of storing and processing is rapidly growing. It allows users to carry an increasing volume of data, the value of this information must be protected from loss, theft or any kind of accident which may occur with the devices, making the backup process a key factor.
In mobile devices the data transmission has a high cost, in price and energy, and this devices depend on batteries, optimizing the bandwidth use is crucial. Deduplication allows substantial reductions in the data volume to be transmitted over network on backup sessions, by identifying common chunks of data, transferring and storing them only once.
On the other hand, usually mobile devices communications use mobile networks, and cloud storage is a viable solution for data backup.
Consequently it is essential the use of cryptographic processes to protect data, during the transmission but also in storage.
This paper proposes a model and a process for measuring the best performance of a safe and energy efficient backup system.
