Decoupling data request rate from hardware medium for archival data storage devices

Abstract:

An archival data storage service identifies, in response to a request to retrieve data previously archived by the service, a set of data storage devices that collectively include the data. From the set of data storage devices, the archival data storage service identifies a set of bins, where a subset of the set of bins includes the data. Based on a deadline for fulfillment of the request, the archival data storage service generates a schedule for retrieval of the set of bins for obtaining the data. The schedule is provided to cause retrieval of the set of bins in accordance with the schedule.
