Abstract: An efficient and scalable method of managing data protection in a geographically distributed storage system is provided using erasure coding. Each zone in the geographically distributed storage system of multiple zones or clusters encodes primary backup chunks replicated from original data chunks in remote zones to create coding chunks. The zone retains one of the coding chunks and distributes the remaining coding chunks to remote zones for future recovery from dual and more complex failures. Upon completion, the primary backup chunks and peer backup chunks can safely be deleted to reduce overhead. Encoding k primary backup chunks to create m coding chunks, and distributing the m coding chunks to different remote zones assures recovery from 1 to m zone/cluster/chunk failures.

Abstract: A computer-executable method, computer program product, and system for managing backups in a distributed data storage system including a first zone, a second zone, and a third zone, the computer-executable method, computer program product, and system comprising processing, at the third zone, a first portion of data of the first zone and a second portion of data of the second zone to create a combined portion of data, and removing the first portion and second portion from the third zone.

Abstract: A computer implemented method, computer program product, and system for providing, via a storage provisioning engine, a scalable objects store enabled to store objects across multiple heterogeneous file arrays; wherein file arrays are enabled to be actively added to the object store without pausing the file arrays; and wherein data representing the objects enabled to be balanced across the heterogeneous file arrays based.

Abstract: In one aspect, a method includes using a file system layer configured to interact with a plurality of volumes and enabling an application to interact with any of the plurality of volumes using a single file system format provided by the file system layer. At least two of the plurality of volumes have different file system formats.

Abstract: In one aspect, a method includes enabling a REST interface to have access to a volume, receiving a request to allow a native file access to the volume and allowing an application to use a native file interface to have access to the volume while preventing the modifications to the volume through the REST interface if the request is received.

Abstract: A method, system, and computer program product for providing, via a provisioning engine, a scalable set of indexed key-value pairs enabled to store objects in a data storage environment; wherein the data representing the objects is enabled to be spread across arrays in the data storage environment; wherein additional arrays are enabled to be added to the data storage environment and included in the indexed key-value pairs; wherein the data stored across the arrays may be balanced.
