What are backup and disaster recovery?
There’s an important distinction between backup and disaster recovery. Backup is the process of making an extra copy (or multiple copies) of data. You back up data to protect it. You might need to restore backup data if you encounter an accidental deletion, database corruption, or problem with a software upgrade.
Disaster recovery, on the other hand, refers to the plan and processes for quickly reestablishing access to applications, data, and IT resources after an outage. That plan might involve switching over to a redundant set of servers and storage systems until your primary data center is functional again.
Some organizations mistake backup for disaster recovery. But as they may discover after a serious outage, simply having copies of data doesn’t mean you can keep your business running. To ensure business continuity, you need a robust, tested disaster recovery plan.
Hit the Data Protection Homerun
It is not a question of if a business will experience data loss; it is a matter of when. Backup is widely employed as the last line of defense to protect against threats like human error, infrastructure failure, or natural disaster. A single threat can cripple a business, whether it is malicious, environmental, or accidental. Backup always provides a necessary safety net.
Disaster recovery (DR) is a specialized solution that focuses on recovery speed to maintain business continuity. While the service is often associated with preparing for natural disasters, there are many use-cases when DR can be effective.
Don’t wait for disaster
Whatever you do, don’t wait to assess your strategies. Backup and disaster recovery plans can help only if they are designed, deployed and tested long before they are needed.
