	att_abstract={{Personal content from mobile devices is often irreplaceable, yet current solutions for managing and synchronizing this data across devices to ensure durability are often limited. For example, one option is to use a cloud storage service such as 
Dropbox to store a master copy and then synchronize each device with this copy.  While common, this model is excessively rigid, forces users to use more expensive cloud storage than is needed, and is oblivious to the different costs of network access by device and time of day. This paper proposes an alternative approach that uses storage on all of a user's mobile devices, home servers, and cloud storage accounts to create a single unified personal storage system called PSCloud which data is automatically cached, replicated, and placed to enable reliable access across all devices while minimizing network access and storage costs. This approach is based on a per-device network context-graph that
tracks connectivity relationships between a user's devices and storage options over time. Preliminary experiments show that combining such  context with techniques that exploit content similarity across devices to make placement decisions can lead to substantial reductions in cloud storage and network usage.}},
