Editor’s note: This is the final post in a blog series by CBT Nuggets trainer Anthony Sequeira that covers IT storage technology.
One of the critical areas we are responsible for as storage experts is keeping key parts of the IT infrastructure operational – in the event of problems. This is referred to as Business Continuity or BC. You cannot make it in the world of storage today without becoming proficient in Business Continuity. But students often struggle in this area, because like so many areas of IT, BC includes its own language. In my final post of the series, I’d like to ensure that you have a firm understanding of key Business Continuity terminology, such as:
- Disaster Recovery. This is where you might be restoring systems, data, and the infrastructure required to support ongoing business operations after a disaster occurs.
- Disaster Restart. The process of ensuring business operations are able to restart with your stored data in a way that is consistent with pre-disaster copies.
- Recovery Point Objective (RPO). A point in time after which systems and data must be recovered after an outage. It helps you define the amount of data loss that a business can endure. A large RPO signifies high tolerance to information loss in a business. Based on the RPO, organizations plan for the frequency of which a backup must be made. For example, if the RPO is 2 hours, backups or replicas must be made at least once in two hours.
- Recovery Time Objective (RTO). This is the amount of time that can elapse before the data must be accessible again. Notice that it’s a measure of how much downtime your business can endure. Notice if you have a very small RTO, you will need to use restore technology that is very fast and sophisticated.
- Data Vault. An offsite location where you can copy or back up data to for use in a Disaster Recovery situation.
- Hot Site. An alternate location where you can run your business. This site will feature all of the hardware and software that you need in order to continue operations seamlessly.
- Cold Site. An alternate location where you can run your business, but where the hardware and software is not operational and must be started in the event of a disaster.
- Server Clustering. Multiple server systems that work together to provide load balancing and high availability configurations.
Until next time, I hope you found this blog series informative, and I’d like to thank you for reading!
