In this capacity he has travelled around the world promoting NetBackup and frequently speaking at user conferences. Know where your backups are located and who is authorized to restore data. Make sure your recovery process is auditable—after a disaster recovery, make sure you can show who had access to the backup data and who performed the recovery. You want to make sure that your planning pays off by making sure that if disaster does strike, everything works as you intend. In the event of a disaster, your connection method to GCP might become unavailable.

Regularly test that the backup path is operational. After you have a DR plan in place, test it regularly, noting any issues that come up and adjusting your plan accordingly. Using GCP, you can test recovery scenarios at minimal cost. It's recommended that you implement the following in order to help with your testing:.

Basics of DR planning DR is a subset of business continuity planning. DR planning begins with a business impact analysis that defines two key metrics: A recovery time objective RTO , which is the maximum acceptable length of time that your application can be offline. This value is usually defined as part of a larger service level agreement SLA.

A recovery point objective RPO , which is the maximum acceptable length of time during which data might be lost from your application due to a major incident. This metric varies based on the ways that the data is used.

For example, user data that's frequently modified could have an RPO of just a few minutes. In contrast, less critical, infrequently modified data could have an RPO of several hours.

This metric describes only the length of time; it doesn't address the amount or quality of the data that's lost. Why GCP? For example, traditional DR planning requires you to account for a number of requirements, including: Capacity: securing enough resources to scale as needed.

From the edge to the cloud – protection anytime, anywhere

Security: providing physical security to protect assets. Network infrastructure: including software components such as firewalls and load balancers.

Support: making available skilled technicians to perform maintenance and to address issues. Bandwidth: planning suitable bandwidth for peak load. Facilities: ensuring physical infrastructure, including equipment and power. Google has one of the largest and most advanced computer networks in the world. The Google backbone network uses advanced software-defined networking and edge-caching services to deliver fast, consistent, and scalable performance.

Multiple points of presence PoPs across the globe mean strong redundancy. Your data is mirrored automatically across storage devices in multiple locations. GCP is designed to scale like other Google products for example, search and Gmail , even when you experience a huge traffic spike.

Managed services such as App Engine, Compute Engine autoscalers, and Cloud Datastore give you automatic scaling that enables your application to grow and shrink as needed. The Google security model is built on over 15 years of experience with helping to keep customers safe on Google applications like Gmail and G Suite.

In addition, the site reliability engineering teams at Google help ensure high availability and prevent abuse of platform resources. Google undergoes regular independent third-party audits to verify that GCP is in alignment with security, privacy, and compliance regulations and best practices. DR patterns DR patterns are considered to be cold, warm, or hot.

How you deal with a flat tire depends on how prepared you are: Cold: You have no spare tire, so you must call someone to come to you with a new tire and replace it. Your trip stops until help arrives to make the repair. Warm: You have a spare tire and a replacement kit, so you can get back on the road using what you have in your car. However, you must stop your journey to repair the problem. Hot: You have run-flat tires. You might need to slow down a little, but there is no immediate impact on your journey. Your tires run well enough that you can continue although you must eventually address the issue.

Design according to your recovery goals When you design your DR plan, you need to combine your application and data recovery techniques and look at the bigger picture. Design for end-to-end recovery It isn't enough just to have a plan for backing up or archiving your data. Make your tasks specific When it's time to run your DR plan, you don't want to be stuck guessing what each step means.

Implementing control measures Add controls to prevent disasters from occurring and to detect issues before they occur. Preparing your software Part of your DR planning is to make sure that the software you rely on is ready for a recovery event. Verify that you can install your software Make sure that your application software can be installed from source or from a preconfigured image. Design continuous deployment for recovery Your continuous deployment CD toolset is an integral component when you are deploying your applications.

Implementing security and compliance controls When you design a DR plan, security is important.

Configure security the same for the DR and production environments Make sure that your network controls provide the same separation and blocking that the source production environment uses. The following list outlines ways to synchronize permissions between environments: If your production environment is GCP, replicating IAM policies in the DR environment is straightforward.

Verify your DR security After you've configured permissions for the DR environment, make sure that you test everything. Make sure users can log in to the DR environment Similarly, don't wait for a disaster to occur before checking that your users can access the DR environment. Train users Users need to understand how to undertake the actions in GCP that they're used to accomplishing in the production environment, like logging in, accessing VMs, and so on. Make sure that the DR environment meets compliance requirements Verify that access to your DR environment is restricted to only those who need access.

Treat recovered data like production data Make sure that the security controls that you apply to your production data also apply to your recovered data: the same permissions, encryption, and audit requirements should all apply. Making sure your DR plan works You want to make sure that your planning pays off by making sure that if disaster does strike, everything works as you intend.

Maintain more than one data recovery path In the event of a disaster, your connection method to GCP might become unavailable.

Test your plan regularly After you have a DR plan in place, test it regularly, noting any issues that come up and adjusting your plan accordingly. It's recommended that you implement the following in order to help with your testing: Automate infrastructure provisioning with Deployment Manager. If you're running your production environment on premises, you need to make sure that you have a monitoring process that can start the DR process when it detects a failure and can trigger the appropriate recovery actions. Monitor and debug your tests with Stackdriver Logging and Stackdriver Monitoring.

GCP has excellent logging and monitoring tools that you can access through API calls, allowing you to automate the deployment of recovery scenarios by reacting to metrics. When you're designing tests, make sure that you have appropriate monitoring and alerting in place that can trigger appropriate recovery actions.

Perform the testing noted earlier: Test that permissions and user access work in the DR environment like they do in the production environmnt. Perform penetration testing on your DR environment. Perform a test in which your usual access path to GCP doesn't work. What's next? Have a look at our tutorials. Was this page helpful? Let us know how we did:.
