A Recovery Point Objective (RPO) is the maximum acceptable interval during which transactional data is lost from an IT service. [11] For example, if RPO is measured in minutes, then in practice, off-site mirrored backups must be continuously maintained as a daily off-site backup will not suffice. [13]
Site Reliability Engineering (SRE) is a discipline in the field of Software Engineering and IT infrastructure support that monitors and improves the availability and performance of deployed software systems and large software services (which are expected to deliver reliable response times across events such as new software deployments, hardware failures, and cybersecurity attacks). [1]
Microsoft Azure, or just Azure (/ˈæʒər, ˈeɪʒər/ AZH-ər, AY-zhər, UK also /ˈæzjʊər, ˈeɪzjʊər/ AZ-ure, AY-zure), [5] [6] [7] is the cloud computing platform developed by Microsoft. It has management, access and development of applications and services to individuals, companies, and governments through its global infrastructure.
Site designation: choice of a backup site. A hot site is fully equipped to resume operations while a cold site does not have that capability. A warm site has the capability to resume some, but not all operations. A cost-benefit analysis is needed. Occasional tests and trials verify the viability and effectiveness of the plan.
A backup site (also work area recovery site [1] or just recovery site) is a location where an organization can relocate following a disaster, such as fire, flood, terrorist threat, or other disruptive event. This is an integral part of the disaster recovery plan and wider business continuity planning of an organization.
Recovery as a service (RaaS), [1] sometimes referred to as disaster recovery as a service (DRaaS), is a category of cloud computing used for protecting an application or data from a natural or human disaster or service disruption at one location by enabling a full recovery in the cloud. RaaS differs from cloud-based backup services by ...
With the consequent reduction in off-site replication bandwidth afforded by deduplication, it is possible and practical for this form of virtual tape to reduce recovery point objective time and recovery time objective to near zero (or instantaneous). Outside of the mainframe environment, tape drives and libraries mostly featured SCSI.
Disaster recovery may refer to: Recovery stage of emergency management; IT disaster recovery, maintaining or reestablishing vital information technology infrastructure;
