Backup Solutions & Disaster Recovery
The purpose of the backup is to create a copy of data that can be recovered in the event of a primary data failure. Primary data failures can be the result of hardware or software failure, data corruption, or a human-caused event, such as a malicious attack (virus or malware), or accidental deletion of data. Backup copies allow data to be restored from an earlier point in time to help the business recover from an unplanned event.
Disaster recovery is an organization’s method of regaining access and functionality to its IT infrastructure after events like a natural disaster, cyber attack, or even business disruptions related to the COVID-19 pandemic. A variety of disaster recovery (DR) methods can be part of a disaster recovery plan. DR is one aspect of business continuity.
TYPES OF DISASTER RECOVERY
Disaster Recovery as a Service (DRaaS): In the event of a disaster or ransomware attack, a DRaaS provider moves an organization’s computer processing to its own cloud infrastructure, allowing a business to continue operations seamlessly from the vendor’s location, even if an organization’s servers are down. DRaaS plans are available through either subscription or pay-per-use models. There are pros and cons to choosing a local DRaaS provider: latency will be lower after transferring to DRaaS servers that are closer to an organization’s location, but in the event of a widespread natural disaster, a DRaaS that is nearby may be affected by the same disaster.
Back Up as a Service: Similar to backing up data at a remote location, with Back Up as a Service, a third party provider backs up an organization’s data, but not its IT infrastructure.
Datacenter disaster recovery: The physical elements of a data center can protect data and contribute to faster disaster recovery in certain types of disasters. For instance, fire suppression tools will help data and computer equipment survive a fire. A backup power source will help businesses sail through power outages without grinding operations to a halt. Of course, none of these physical disaster recovery tools will help in the event of a cyber attack.
