Personal cloud storage systems, like Dropbox, are revolutionizing the way people think about and access their files. As the prevailing model, these systems use unicast to push file changes to each of the "unsynced" devices. And as a result, they transmit multiple times the same information, once per unsynced device. This puts an unnecessary strain on outgoing bandwidth at the datacenters. One way to address this is to leverage P2P-like content distribution to benefit from user resources at the edges of the Internet. Although protocols like BitTorrent have proven to be effective in this scenario, we go a step further in this work and propose cross-swarm bundling as a mechanism for file distribution. One key contribution of this work is that, instead of using bundling as means to extend the lifetime of swarms, we show that it can be useful to improve the Quality of Experience (QoE). We validate our proposal using a trace of Ubuntu One, a real personal cloud system, obtaining significant improvements on the QoE levels.
