Personal storage is a mainstream service used by millions of users. Among the existing alternatives, Friend-to-Friend (F2F) systems are nowadays an interesting research topic aimed to leverage a secure and private o-site storage service.

However, the specic characteristics of F2F storage systems (reduced node degree, correlated availabilities) represent a serious obstacle to their performance. Actually, it is extremely dicult for a F2F system to guarantee an acceptable storage service quality in terms of transference times and data availability to end users. In this landscape, we propose resorting to the Cloud for improving the storage service of a F2F system.

We present FriendBox: a hybrid F2F personal storage system. FriendBox is the rst F2F system that eciently combines resources of trusted friends with Cloud storage for improving the service quality achievable by pure F2F systems.

We evaluated FriendBox through a real deployment in our university campus. We demonstrated that FriendBox achieves high transfer performance and exible user-dened data availability guarantees. Furthermore, we analyzed the costs of FriendBox demonstrating its economic feasibility.
