Gartner defines distributed file systems and object storage as software and hardware solutions that are based on “shared nothing architecture” and that support object and/or scale-out file technology to address requirements for unstructured data growth. A shared-nothing architecture is a distributed computing architecture in which there is no single point of contention across the system. Distributed file system storage uses a single parallel file system to cluster multiple storage nodes together, presenting a single namespace and a storage pool to provide high-bandwidth data access for multiple hosts in parallel. Data is distributed over multiple nodes in the cluster to deliver data availability and resilience in a self-healing manner, and to provide high throughput and scale capacity linearly. Object storage refers to devices and software that house data in structures called “objects,” and serve clients data via RESTful HTTP APIs, such as Amazon Simple Storage Service (S3) and OpenStack Swift.
Gartner’s view of the enterprise backup and recovery software solution market is focused on transformational technologies or approaches delivering on the future needs of end users. It is not focused on the market as it is today. Gartner defines the market as follows: Backup and recovery software solutions are designed to capture a point-in-time copy (backup) of an enterprise workload and write the data out to a secondary storage device for the purpose of recovering this data in case of loss. The solution can be offered as an appliance, as software only or as a vendor-managed service offering.
Enterprise information archiving (EIA) solutions are designed for archiving data sources to a centralized platform to satisfy information governance requirements, including regulatory and/or corporate governance and privacy; improve data accessibility; surface new data insights; and gain operational efficiencies. There are several core capabilities of this market. They include archiving digital communication content, such as email, workstream collaboration, instant messaging (IM) and SMS; classifying data and enabling retention management of archive content; creating a searchable index of content; and providing basic tools for e-discovery and supervision.
