A disaster recovery plan is an essential component of the IT strategy of any business and is becoming more and more essential as the events of network outages and security breaches have increased.
In the initial stages of disaster recovery planning, often there is a mistake regarding what a disaster recovery plan is made of. Several times decision makers often wrongly think that the data backup is an adequate precaution when a disaster occurs.
Although a backup strategy is essential, it’s different from a disaster recovery planning. So, you should understand what the differences between backup and disaster recovery plan are.
- Ability of Recovery
Disaster recovery is a practice of failing over your major environment that has the capability of sustaining the continuity of your business.
Backups are helpful for instant access in the event of the requirement to restore a document but don’t support the failover of your entire environment in case, if your environment becomes compromised. They even don’t include the physical resources needed to bring them online.
- Planning Process
The planning process for a backup is comparatively simple because often the only goals to meet are the data retention requirements and recovery point objective (PRO).
A total disaster recovery strategy as designed by a company like CloudEndure needs extra planning, including creating recovery order, communication process, determining which systems are considered critical and most importantly, a method to conduct a valid test.
- Data Retention Requirements
Typically backups are performed on an everyday basis to get the assurance of required data retention at a single location, with the sole intention of copying data.
Disaster recovery, on the other hand, needs the determination of the recovery time objective (RTO) so as to entitle a maximum length of time the organization can be without IT systems after a disaster. Customarily, the ability to fulfill the provided RTO needs at least one replica of the IT infrastructure in another location to allow duplication between the DR site and production.
- Additional Resource Requirements
A backup is just a copy of data needed to be restored to the original source. DR, on the other hand, needs a separate production environment in which the data can live. You have to consider all aspects of the present environment including software, physical resources, security, and connectivity.
The general importance and benefits of a DR plan are to reduce the risk and downtime, avoid outages and maintain compliance, whereas backups have a simpler purpose. Thus you have to make sure you understand which solution is right for your business requirements.
