Incorporating Data Protection, Availability, and Retention with a 3-2-1 Strategy

Written by Tyler Moore

The optimal strategy for incorporating data protection, availability, and retention in your cloud backup plan.

Cloud infrastructure can fail, accidental data deletions can occur, a multitude of other human errors can happen, and malicious attacks can occur resulting in data loss, data inconsistencies, and data corruption. That’s why any cloud data storage platform must incorporate redundant processes and procedures to keep your data available and protected. On top of that, regulatory compliance and certification requirements may also dictate that data be retained for a certain minimal length of time, often for several years.

All cloud data storage providers should protect data and ensure business continuity by performing periodic backups. If a particular storage device fails, the analytic operations and applications that need that data can automatically switch to a redundant copy of that data on another device. Data retention requirements call for maintaining copies of all your data. 

But that’s not all, single copy backup is not enough. A complete data protection strategy should go beyond merely duplicating data within the same physical region or zone of a cloud compute and storage provider. It’s important to triple replicate that data among multiple geographically dispersed locations to offer the best possible data protection. This is because the much touted “triple redundancy” offered by some cloud vendors won’t do you any good if all three copies of your data are in the same cloud region when an unforeseen disaster strikes. For optimum risk mitigation and disaster recovery you should follow a 3-2-1 strategy of triple replication, utilizing two types of media, and at least one copy geographically dispersed. 

Finally, pay attention to backup performance. Data backup and replication procedures are important, but if you don’t have the right technology, these tasks can consume valuable compute resources and interfere with production analytic workloads. To ensure the durability, resiliency, and availability of your data, a modern cloud data storage platform should manage replication programmatically in the background, without interfering with whatever workloads are executing at the time. Good data backup, protection, and replication procedures minimize, if not prevent, performance degradation and data availability interruptions.
