Cloud Disaster Recovery: Turn Backups into a Tested Business Recovery Plan

The backup dashboard displays green ticks. Then the application goes offline, and the team realizes that recovering the database is just one aspect of resuming operations. The application's configuration is lost, access to an essential account is impossible, and no one knows if customers' emails were delivered already. The backups are there, but the company cannot continue its regular routine anyway.

Cloud disaster recovery planning addresses the wider problem described above. It relates to the technical recovery of the company's systems, the processes that need to be done by the company, the data it is ready to lose, and the time to restore a functioning system. Such a plan requires proof of testing, assignment of roles, and communication of uncertainties. Just buying the backup storage is not enough for that.

The below guide provides a description of how backups may be transformed into a recovery plan for a growing business. Objectives, dependencies, access, restore testing, runbooks, reconciliations, and maintenance will be discussed here. The examples given are just illustrations and have nothing to do with the realities of recovery at Digitonix customers. It is your environment and constraints that will allow you to define which recovery tasks are the most important for you.

Define the business activity that should be recovered

Start with a practical activity that should be recovered, like order processing, service call registration, and giving access to customer accounts to employees. Specify what is needed for this activity to be performed and what is a partial recovery in terms of it. Just because the homepage is available, it doesn't mean that an order could be processed by the client.

Identify which activities are able to be deferred while some require an immediate solution. A manual data entry system will do for some activities as long as there is proper documentation and reconciliation. For other activities, real time data will be required. Prioritization should happen before the event forces people to do so in an emergency situation. It should not just be about the listing of servers on the plan but about the business considerations as well.

Establish recovery goals with assumptions stated

Recovery time objective defines the goal for how long will it take to restore the necessary services. Recovery point objective refers to the goal for the data restoration gap size. This is a plan goal, not a guarantee that comes automatically with the use of cloud services. Clearly define the scenario of the incident and measurements behind the goals.

Consider the costs and operations related to tighter goals. More frequent backups or a different environment will increase the necessary investments in infrastructure and testing. Determine whether the services should have different goals. Reporting will be more tolerant of a certain difference than order processing. Record the agreement within the business about such choices, and reconsider them when the purpose of the product and the customer requirements change.

Create the dependencies graph that includes people

The list of databases, application services, files, configuration, domains, certificates, identity system, and external systems required by the critical workflow should be listed. Indicate the order in which the components should come up. The service can start working fine but fail all practical requests due to a lack of one component. Compare the graph with a real-life journey of a customer rather than with just the labels of the infrastructure.

Identify the personnel and access required to conduct the recovery operation. Should there be any issues with the availability of the only authorized operator, the technical plan can get stalled. Make sure the proper backup procedures and access are documented. Ensure all of that within the boundaries of the company's security policy. What you need to achieve is an achievable authorized recovery rather than creating universal access.

Be familiar with the content of your backup files

Be clear about the scope, frequency, retention period, storage location, and verification of the process of taking the backups. Be sure that you know the difference between a database backup, file backup, configuration or infrastructure backup. Ensure that you really have all the components needed for the critical process.

Ask what is the relationship between schema and applications version and the backup you recover. Your database image will likely need to be compatible with the application version or follow migration steps. Document this requirement and test it. If your attachments exist outside your database, make sure that there is no discrepancy between them and restored records. Recovery operation that results in records that reference non-existent documents is technically sound but practically useless for business purposes.

Secure your backups and recovery process

Examine who can create, view, change, and delete recovery data. Restrict access based on role and retain access controls that are suitable for this environment. Consider the behavior of your backup plans in case of compromise of a regular application account. The particular architecture should reflect your business needs and chosen provider's capabilities with evidence that required controls are in place and functioning.

Add encryption and key access to the dependency map. If the recovery team cannot access the authorized methods to decode the backup, then the backup will not help at all. Test the procedure without revealing any secrets in a runbook or support discussion. Ensure that there is documentation regarding the person who holds the keys and accesses and the review process for changes to them to avoid accidentally creating a dependency on an outdated procedure while performing regular security updates.

Select a recovery pattern for the real service

There can be a number of possibilities ranging from restoring backups in a new environment to using a more prepared alternative environment. It will depend on objectives, dependencies, costs, and capabilities. Do not choose the most complex design simply because it looks highly available on paper.

For AWS applications, the AWS disaster recovery overview will offer a background on the options that are possible. Please check the current service documentation for details regarding the design. Digitonix's AWS capabilities, Azure capabilities, and Google Cloud capabilities can all be reviewed in conjunction with the existing platform. It is important to remember the operating plan irrespective of the provider.

Rebuilding infrastructure from definitions maintained

Where possible, have the infrastructure and the configurations defined in such a manner that they can be used to recreate the environment. Determine what falls out of these definitions, such as external accounts or manually managed configurations. Do not assume that simply because there is a repository containing the deployment scripts, that everything will be recreated automatically.

Document environment-specific value settings and how authorized operators retrieve them. Keep sensitive data in appropriate control systems instead of duplicating them in procedural documents. Determine if the restored data is accessing the desired network, permissions, and services. Incorrectly restoring an application within a technically possible architecture may lead to confusion and possibly business transactions if it accesses production integrations without being ready by the recovery team.

A runbook under pressure

Define a series of sequential steps with their prerequisites, expectations, and decision points. Explain how will the operator know if the step is done correctly, and what should he do if not. Don’t forget to add contact and escalation processes relevant to your business. A list of cloud console URLs can be helpful, but not a recovery process in any way since it does not address the issue of gaps of understanding for the operator regarding some parameters/values/actions.

Have a second person review the runbook in the approved testing environment, who is not an author. List points where the reviewer needs to ask for some clarification of a point that was presumed clear enough by the author. Adjust the runbook according to the results of your research. Make sure to have traceability of all versions and dates of updates. The runbooks must evolve together with the application; a great runbook for the previous year’s architecture may not apply anymore due to changes in the database, service provider, and authentication.

Test restoring as a complete user experience

Restore to an approved environment and test the required business process. Ensure that test restoring covers application access, sample records, attachments, permissions, and any integrations. Make sure that the test does not inadvertently trigger notifications to actual customers or generate operational orders unless this is what the test is intended to do. This testing boundary should be defined ahead of time by the person owning the testing.

Identify the phases in which the recovery process is undertaken – detection, authorization, infrastructure set-up, data restoration, validation and resumption of services. Document the actual timeline and difficulties encountered rather than just the result. AWS guidance on disaster recovery testing supports practicing the plan. Leverage the insights from the test to revise objectives, architecture and processes where there is a discrepancy between the two.

Data completeness and application sense

Review a sample of records versus the recovery point. The goal is to search for relationships which are critical to business such as an order with line items, a case with attachments, or an invoice with its status. Counting records may be insufficient in proving the absence of relationships and compatibility problems with the data. Discuss with application users the criteria of acceptance.

Think about the actions taken outside the restored database. Some payment provider, email provider, or partner's systems could perform some action past the recovery point. Recovery of the older state of the local data doesn't undo this external action. Prepare for dealing with this difference before repeating the requests. This applies especially in case where the application will be sending messages or initiating shipments.

Make the decision to resume service explicit

Delegate responsibility to declare the recovered service as operational. The decision will need to be based on the predefined validation criteria and limitations. Technical personnel will verify that systems are up and operational, whereas operations personnel will verify that the key workflow is working. Keep remaining limitations visible and describe any temporary service restrictions. Ambiguous readiness decision might cause confusion between different teams, who will be providing different information to the customer.

Create templates that will allow customizing messages according to the real incident. Describe what service is affected, what the customers can do, and when the next update will be sent according to the process of the organization. Do not make up deadlines for the end of recovery operations before the team receives evidence. Proper incident communication allows taking actions based on what is already known while keeping the possibility of plan adjustment in mind.

Failback and reconciliation planning prior to incident

Reversing from the recovery environment back to the normal environment is also a significant change requiring its own plan. Identify where the work is logged during recovery and how it gets to the target environment. Make sure there is no situation where the changes are independently accepted by two different environments without any reconciliation plan.

Check for an effective return path as appropriate, including documentation from the recovery exercise. Identify those steps that require coordination with outside systems or customers. A recovery design that is only effective until normal processing resumes is missing an essential component. Plan failback as part of the business continuity discussion, assigning responsibility and demonstrating that the transition can preserve the work done during the recovery process.

Review the recovery arrangements themselves

Identify alerting for backup failures, gaps in backups, expiry of access agreements and other such issues which can undermine the plan. Work out how to contact the responsible party and the action they need to take. A message which is sent to a vacant mailbox will serve little purpose. Make sure that backup completion, restore readiness, and infrastructure drift can be detected based on the recovery plan.

Keep the monitoring process comprehensible to the team performing the function. Document the latest successful restore test and any outstanding issues. Be sure that provider and application changes are part of the review process. Cloud and DevOps services can aid in implementation and operation monitoring; meanwhile, consider cybersecurity services for the access and security considerations surrounding the recovery process design.

Include costs and staffing in the plan

Consider costs and personnel required for the chosen option on a recurring basis. Factor in exercises and maintenance, not only the monthly cost of the alternative environment. Tighter targets may call for more preparation and discipline. Frame the trade-offs in terms of the supported activity and recovery assumptions to make cost decisions in context, not merely as comparisons of cloud prices.

Question the team about its ability to sustain the proposed architecture. The overly complex design may result in more potential failure modes if the design is not used by anyone and modifications are made to it. It is critical to recognize training needs and external support needed prior to implementation. In case your plan involves a provider or supplier reaction, you should document the real scenario of receiving such support and not rely on an automatic response that is not agreed upon in advance.

Maintain usefulness and feasibility of exercises

Decide on the scope that addresses the key uncertainty. For example, one exercise may confirm the successful restoration of a database and the correct version of application software, while another exercise may confirm the operator's execution of the runbook procedure without assistance of the runbook author. Determine criteria for success and gather evidence. Don't treat each exercise as a catastrophic simulation.

Review the results with both the technical and business owners. Assign an action and owner for each issue discovered. Then verify the completion of each action during the next suitable review meeting. It is no good going through the exercise again without resolving any existing issues, The value comes from improving the plan and the team's ability to use it, rather than recording repeated tests that leave known issues unresolved.

How Digitonix can help with cloud recovery planning

Put together a quick evidence pack for the meeting. This should include a recent backup test, the previous restore test result, a dependencies map, and the version of the application used in that test. Label anything that is unknown rather than making assumptions. That allows the discovery process to concentrate on the actual knowledge gaps and not build a solution based on unproven capabilities.

Bring your critical workflows, infrastructure inventory, existing backup solution, access mechanisms, and recovery objectives. It will be possible to approach Digitonix to get assistance with dependency identification, implementation, runbooks, and testing recovery of your environment in controlled conditions. You should request the proposal with information on acceptance criteria, operational responsibility, and assumptions made for the systems supported by the third-party provider.

Study the Digitonix service portfolio and technology overview, after that get in touch with the Digitonix team with the recovery workflow you would like to implement. Software development work may be needed for reconciliation or recovery checks inside the application. You need to get the plan that can be executed and managed by the team with all limitations clearly identified. See contact the team for related information.

Questions frequently asked

Is it enough to have successful backups in place for disaster recovery?

No. Backups are crucial, yet recovery also relies on infrastructure, compatibility, accessibility, configuration, third-party services, validation, and operational choices. Perform a test on a full, practical workflow within an appropriate environment. The outcome should include the scope of what can be recovered, the data gap, time required, and still unmet restrictions. A successfully run scheduled backup operation does not prove these capabilities.

What is the difference between RTO and RPO?

RTO is the desired timeframe to recover the necessary service level, whereas RPO stands for the desired limitation on the data gap. Specify the points of measurement and assumptions behind these values in relation to the incidents under consideration. These are the objectives that need to be met by the architecture and processes.

Should every application maintain a second live environment?

Recovery strategy will depend upon business needs, cost, interdependencies, and capability of the team to implement it. While some services can be restored using backup restore process, others require better-prepared strategies. Evaluate the candidates for your specific scenario and verify against objectives and the selected approach. Having other environments ready is not enough – synchronization, permissions, validation, and decision to restore the service require their own plans.

How often should we test our recovery strategy?

Pick a frequency depending upon the significance of the service, rate of changes, and organizational needs. Schedule tests in response to material changes that influence assumptions about the recovery strategy, and document open issues prior to each test. The schedule should be established among owners of the service. Good test responds to an identified risk and provides evidence, not just another checkmark on calendar.

What questions should we ask from the recovery implementation vendor?

Ask about the business process that will be demonstrated, the scope of recovery involved, the person that will authorize and execute the solution, and how external events are coordinated. Ask for runbook and failback support, proof of acceptance, recurring costs, and maintenance requirements. Assume the same things when evaluating competing solutions. Just the diagram or list of backup software isn’t sufficient to judge ability to recover operations.
