Disaster Recovery Testing – What’s it all about and why it is a top priority.
What is disaster recovery testing?
Disaster recovery testing can be the reality behind the theory of business continuity and backup strategies. Meaning; the fundamental core with any sort of business is configuring and maintaining regular backups of critical data.
While focus on the backup side of data protection occurs; the overall puzzle is larger. A backup may not be useful if the data isn’t accessible in a live DR situation.
The other side of the coin is restore and recovery of data which in the eyes of most is the critical task – if data recovery fails; then it may not be worth running through all the steps leading up to that point?
What’s the value in disaster recovery testing to businesses?
There are a number of benefits that come about from performing regular disaster recovery testing tasks:
- Validation that the backup strategy and business continuity plan will work successfully.
- Finding any unexpected issues with the recovery process.
Documentation is usually written with the fastest way home. Preventing any unexpected issues through DR testing will reduce downtime overall.
- Knowing how resilient the business is in the event of a disaster scenario.
Knowing how much data loss (RPO) and time taken (RTO) to get operations running again. As a result it’s easier to get an idea what would bring the business down.
What are the different types of disaster recovery testing?
Scenarios come in many different forms. The main things to focus on are realism, complexity and urgency so that it’s as close to a real life DR scenario as possible.
This is stressed by TechTarget as well which can be accessed here.
How regularly should disaster recovery testing occur?
Monthly disaster recovery testing is best practice – which TestMyBackups echos.
As outlined earlier; there are many different ways and theories on how often disaster recovery testing is performed, Shirley Zhang at DataNumen has outlined a few different views around this.
In most instances it comes down to the individual business on how regularly these occur.
However; one question we regularly ask when it comes to disaster recovery testing frequency is…
How valuable is your data?
Is your business able to survive and thrive during a critical system outage? If an outage was indefinite and there was an issue during recovery?
As a general rule; data loss leads to lost productivity and profit – basically throwing money away (or worse to your competitors).
In conclusion if you’ve answered yes to either of these; contact us with your enquiry – no obligation. All the disaster recovery testing required can be performed effectively in co-operation between your business and our team.
