The Importance and How to Offsite Backup | Disaster Recovery Scenarios
When thinking about disaster recovery and protecting backup data, we always want to have more than one source of being able to restore our production systems. There is an industry suggested standard of the 3–2–1 rule that says we ideally have three copies of our data on two different mediums, and one offsite copy of that backup data. This rule of thumb that is used often helps us to appreciate that we want to diversify our backup sources so that we don’t have all of our recovery options relying on one source, medium, or backup location. This is extremely important to consider when thinking about building our disaster recovery plans and thinking through how to design our backup strategy. We want to dive a bit deeper into the offsite backup aspect of our backup solution as it is critically important. What are some disaster recovery scenarios that make having offsite backups important? What are some technologies that we can use for offsite backup? How do we implement offsite backup?
