Data Backup And Disaster Recovery Solutions – Whether it’s an unexpected failure, a malicious attack, or a natural disaster, your data is naturally vulnerable to deletion or corruption. By taking a proactive approach to data loss prevention, you ensure that you have a data recovery model and recovery plan in place.
Without your critical information, your business could lose revenue. In the worst case scenario, the inability to restore lost data can force you to close your business for good.

In a previous blog post, I presented four disaster recovery strategies. These strategies will help you prepare for and recover from a disaster. By using the best practices outlined in the Good Reliability white paper to design your DR strategy, your workloads can remain available despite catastrophic events such as natural disasters, technical failures, or acts of God. humans.
As shown in Figure 1, storage and retrieval are associated with higher RTO (recovery time) and RPO (recovery point). This results in a long time and a lot of data loss between the time of a disaster event and recovery. However, backup and restore may still be the right strategy for your workload because it is the easiest and least expensive to implement. Additionally, not all jobs require an RTO and RPO of minutes or less.

Backup provides a central view where you can organize, schedule, and monitor the backup of these resources. Your RPO is determined by how often the backup runs.
Each region consists of several Access Zones (AZs). A Multi-AZ strategy that restores resources across AZs is essential to ensure High Availability (HA).
An HA strategy provides most of your workload’s DR needs in one place. However, catastrophic events include human actions and software errors that can delete or corrupt your data. When this happens, HA strategies return these types of data errors. So for DR, you need to store the regional database as well (Figure 2). By using a backup that provides point-in-time restore (such as Amazon DynamoDB’s point-in-time restore and RDS’s backup DB instance ), or enabling the version (using the version of Amazon’s simple storage service (Amazon S3) buckets), you can “roll over” to get a good detected state.
In addition to central storage management, the backup allows you to copy all regions and accounts, as shown in Figure 2. By copying data to another region, you can handle the largest scale of disasters. If a crash prevents your load from operating in an area, the load can be returned to the recovery area (Figure 3) and operated from there.
Surprising Data Backup Statistics
You must use a different account from your primary region with different credentials for your recovery region. This can prevent human error or an error in one region from affecting others.
Recovery time (and therefore RTO) is often understood as the time required to recover from workloads and take over failed services. However, as shown in Figure 4, failure detection time and failure decision time are additional (and possibly significant) contributors to recovery time.
To minimize recovery time, diagnosis should be automatic. Don’t wait for your operators to notice a problem, never wait for your customers to notice.
In Figure 5, we show a possible framework for detecting and responding to events that affect the availability of your workload.
Data Backup & Disaster Recovery
Amazon EventBridge supports events from multiple services and targets actions in response to those events. Two event sources are used here:
Figure 5 shows that we can perform multiple actions as a result of these events. We can track the event by creating an OpsItem in the Systems Manager. Or we may notify developers and operators by using Amazon Simple Notification Service (Amazon SNS) to send them an email or text message. There are several options for direct response. Lambda can run code, or Systems Automation Manager can be activated to run real scripts that perform tasks such as launching EC2 instances or deploying CloudFormation packages.
Restoring data to a database creates resources for that data, such as EBS volumes, RDS DB instances, and DynamoDB tables. Figure 6 shows that you can use Backup to restore data in the recovery area (in this case the EBS volume). Infrastructure reconstruction includes the creation of resources such as EC2 instances, in addition to Amazon Virtual Private Clouds (Amazon VPCs), subnets, and security groups.
You must use Infrastructure as Code (IaC) to recover the infrastructure in the recovery area. This includes using CloudFormation and the Cloud Development Kit (CDK) to build infrastructure consistently across regions. To create EC2 instances for your workload needs, use Amazon Machine Images (AMIs) to add the required operating system and packages. Because these AMIs contain what you need to build regular servers, we call them “Golden AMIs.” Amazon EC2 Image Builder can be used to create gold AMIs and copy them to the recovery pool.

In some cases, you will need to re-integrate infrastructure and data. For example, in Figure 6, we have returned the state data of the EBS volume. We want to attach this volume to the EC2 instance. Figure 7 shows one possible way.
We are implementing a serverless solution using EventBridge. The repository will generate an event when the recovery data for the resource is complete. In response, EventBridge initiated two actions: 3A) creating an OpsCenter entry to monitor and 3B) invoking a Lambda function. From the event, Lambda receives the ID of the new resource created in the recovery pool, as well as the ID of the pool used for recovery (recovery location). The Lambda code calls the API to get the label on the original resource (primary state), which can guide you when configuring the interface. The backup will automatically copy the tags from the source to the backup it creates. By calling another CloudFormation API, Lambda can find out the identity of the EC2 instance. It can then make API calls to Amazon EC2 and mount the EBS volume.
Figure 7 shows how to attach an EBS volume to an EC2 instance, but there are other interactions you may want to automate. For example, instead of a Lambda function, a data refresh event can trigger a Runbook in Systems Manager. This will automatically mount the recovered EFS file system or Amazon FSx to one or more EC2.
For more complex automation, you can use Action Functions to automate everything. This includes infrastructure setup using CloudFormation, data recovery using backup, and integration steps. With Step Functions, you configure the state machine that executes Lambda functions to run and monitor each function as desired with the desired dependencies.

A failover redirects production traffic from the primary state (where you have determined that the workload cannot continue) to the recovery state. This will be discussed in a future blog post.
As business and technical teams collaborate on DR goals and implementation, consider using a backup and recovery strategy to meet the DR needs of your workload. With automation, you can reduce RTO and thereby reduce the impact of downtime in the event of a disaster. The low cost and simple implementation of this strategy makes it a good choice for many workloads. Things happen. Your city has been hit by a storm or the technology has failed due to age or lack of maintenance. Or perhaps worse, a cyber attack compromises your system and holds your data for ransom. Any number of threats can steal your data from your care,
