Minimizing downtime and data loss during disaster recovery is typically measured in terms of two key concepts: Recovery time objective (RTO), time until a system is completely up and running; Recovery point objective (RPO), a measure of the ability to recover files by specifying a point in time the backup copy will restore to.
IT disaster recovery (also, simply disaster recovery (DR)) is the process of maintaining or reestablishing vital infrastructure and systems following a natural or human-induced disaster, such as a storm or battle. DR employs policies, tools, and procedures with a focus on IT systems supporting critical business functions. [1]
Tier 0 – No off-site data • Businesses with a Tier 0 Disaster Recovery solution have no Disaster Recovery Plan. There is no saved information, no documentation, no backup hardware, and no contingency plan. Typical recovery time: The length of recovery time in this instance is unpredictable. In fact, it may not be possible to recover at all.
The most desirable RPO would be the point just prior to the data loss event. Making a more recent recovery point achievable requires increasing the frequency of synchronization between the source data and the backup repository. [65] Recovery time objective (RTO): The amount of time elapsed between disaster and restoration of business functions ...
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. [2]
Disaster recovery may refer to: Recovery stage of emergency management; IT disaster recovery, maintaining or reestablishing vital information technology infrastructure; Disaster draft, disaster recovery plan for professional sports teams
Hybrid Online Backup works by storing data to local disk so that the backup can be captured at high speed, and then either the backup software or a D2D2C (Disk to Disk to Cloud) appliance encrypts and transmits data to a service provider. Recent backups are retained locally, to speed data recovery operations.
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 ...
