Abstract: Techniques for chunking data in data storage systems that provide increased data storage security across multiple cloud storage providers. The techniques employ a chunking engine and a policy engine, which evaluates one or more storage policies relating to, for example, cost, security, and/or network conditions in view of services and/or requirements of the multiple cloud storage providers. Having evaluated such storage policies, the policy engine generates and provides operating parameters to the chunking engine, which uses the operating parameters when chunking and/or distributing the data across the multiple cloud storage providers, thereby satisfying the respective storage policies. In this way, users of data storage systems obtain the benefits of cloud storage resources and/or services while reducing their data security concern and optimizing the total cost of data storage.

Abstract: Described are methods, systems, and apparatus, including computer program products for analyzing system dumps. A method for analyzing a first system dump is performed by a computing system. The first system dump is received by the computing system, the first system dump generated by a first server in response to the first server detecting a first error. First diagnostic data are extracted, by the computing system, from the first system dump, the first diagnostic data comprising at least first call stack data for the first server. Second diagnostic data are identified by the computing system that are indicative of the first error by comparing the first call stack data of the first diagnostic data to second call stack data of the second diagnostic data.
