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).

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.
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 ...
Simplified Disaster Recovery (SDR) Guided Search and Restore: Built-in indexing and the ability to restore files through search. True image restore; Cloud Support [22] Free S3 Cloud Connector for Backup Exec to back up data to an S3-compatible cloud storage; Free Azure Cloud Connector for Backup Exec to write data to Microsoft Azure cloud storage
hybrid cloud solutions that replicate both on-site and to off-site data centers. This provides instant fail-over to on-site hardware or to cloud data centers. high availability systems which keep both the data and system replicated off-site, enabling continuous access to systems and data, even after a disaster (often associated with cloud storage).
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.
A configuration management database (CMDB) is an ITIL term for a database used by an organization to store information about hardware and software assets (commonly referred to as configuration items). It is useful to break down configuration items into logical layers. [1]
This configuration typically requires the most extra hardware. N+1 — Provides a single extra node that is brought online to take over the role of the node that has failed. In the case of heterogeneous software configuration on each primary node, the extra node must be universally capable of assuming any of the roles of the primary nodes it is ...
