RAIC Integration for Network Storages on Mobile Devices

Systems to combine multiple network and online storage targets with implied redundancy, security and fault tolerance, so-called RAICs, have recently seen renewed discussion due to the growing popularity of convenient Cloud Storage service offerings. For mobile device access to RAICs, less research results are available. A "smartphone for the future" with pervasive storage availability should be intelligently and autonomically connected to the Cloud. Such a constellation allows access without great expenses to multiple applications, data, and further resources so that the requirements of the users (security, privacy, safety, pricing, vendor selection, etc.) as well as the functional user objectives are rewarded in the best way. In addition, valuable battery capacities can be saved by selecting appropriate algorithms and parameters and by placing parts of the RAIC integration into the infrastructure. Using the example of distributed data storage, including specific resources services with versatile features such as extended storage capacity, backup, synchronization and collaborative sharing of data, we propose a mobile, energy-efficient and autonomic RAIC integration concept. Its effects are being evaluated with a storage controller on a smartphone.
