Gartner defines backup and data protection platforms as technologies that capture point-in-time copies of enterprise data for the purpose of recovering it from multiple data loss scenarios, enhancing data protection initiatives, and expanding data insights and access capabilities. These technologies protect enterprise data, applications and infrastructure in hybrid, multicloud and SaaS environments. Backup and data protection platforms are available as software-only, integrated appliances and vendor-developed and hosted backup as a service (BaaS).
Network video recorders (NVRs) are IP-based appliances that are purpose-built for managing cameras, recording and viewing camera feeds at a site. NVRs are usually PC-grade or low-end server systems made using commercial off-the-shelf (COTS) hardware components. They usually contain an embedded operating system or a client operating system that hosts video management software, which provides users a mechanism to view, record and manage camera feeds.
Server virtualization includes a range of technologies that abstract an underlying infrastructure layer (networking, storage and compute [including memory]). In doing so, it improves hardware utilization, workload portability, automation and availability. Server virtualization is most often associated with hypervisor-based server workloads running in data center environments on industry-standard servers. In reality, server virtualization incorporates multiple technologies, spans locations from public cloud to edge, and supports initiatives for both cloud-native transformation and infrastructure modernization. It includes hardware-, cloud- and software-based technologies.
