The Archistar Secret-Sharing Backup Proxy


Andreas Happe, Florian Wohner and Thomas Loruenser


Cloud-Storage has become part of the standard toolkit for enterprise-grade computing. While being cost-and energy-eecient, cloud storage's availability and data conndentiality can be problematic. A common approach of mitigating those issues are cloud-of-cloud solutions. Another challenge is the integration of such a solution into existing legacy systems. is paper introduces the Archistar Backup Proxy which allows integration of multi-cloud storage into existing legacy enterprise computing landscapes by overloading the industry-standard Amazon S3 protocol. e paper provides multiple lessons-learned during implementation and concludes with a performance evaluation with traditional backup solutions utilizing redundant remote storage.
