What is Disaster Recovery?
Disaster Recovery is the process of restoring business services following a disaster event in which the primary operational facility has been impacted, either partially or totally.
Disaster Recovery is typically a costly and complex solution to implement, with the traditional Disaster Recovery model generally including the following infrastructure components:
- A secondary datacentre facility.
- Inter-site connectivity services, for example dark fibre or managed Ethernet service.
- Wide Area Network and Internet services.
- Network Switching and Routing.
- Compute and Storage resources.
- Storage Area Networking.
- Firewall and Security resources.
- Backup and Recovery hardware.
In addition, there are a number of soft components required to facilitate the overall Disaster Recovery solution in the traditional model, adding to the overall investment and environmental complexity, namely:
- One or more replication technologies for data duplication between the Primary and Disaster Recovery sites.
- Software licensing for the operation of Disaster Recovery infrastructure components.
- Vendor support contracts for Disaster Recovery site hardware and software assets.
One of the most common issues with Disaster Recovery solutions is that they are often implemented with minimal business engagement. As a result, organisational recovery targets are commonly not defined or achievable, including:
- Recovery Point Objective – the maximum acceptable level of data loss following an unplanned event, such as a disaster, act of crime or terrorism, or any other business or technical disruption that could cause data loss. The RPO represents the point in time to which lost data can be recovered.
- Recovery Time Objective – the period of time in which business systems must be recovered to the Disaster Recovery facility following an unplanned event or disaster. An RTO typically consists of multiple smaller RTOs based on the priority of each system together with its dependents and dependencies.
Traditional Disaster Recovery solutions require significant infrastructure investments, introduce additional environmental complexities and often don’t meet business Recovery Objectives.
Disaster Recovery as-a-Service, by MOQdigital, assists organisations to facilitate system restoration following an outage or disaster event, whilst reducing the cost and complexity associated with traditional Disaster Recovery solutions and ensuring that business Recovery Objectives are appropriately catered for.
