Tutorial / Cram Notes
A well-defined schedule and retention policy ensure that backups are created at regular intervals and are retained for the duration necessary to meet business continuity, compliance, and regulatory requirements.
Creating a Backup Plan
When establishing schedules and retention for AWS Backup, the first step is to create a backup plan. This plan defines when and how backups are taken. A backup plan includes:
- A backup rule with a schedule for when backups are to be taken (e.g., daily, weekly, monthly).
- A retention rule that specifies how long each backup is to be kept.
- Optional lifecycle rules to transition backups to cold storage to save on costs.
Backup Rule
A backup rule in AWS Backup contains details about how frequently the backups are created and when they should occur. For instance, you might configure the following parameters:
- Frequency: How often the backup should occur (e.g., every 12 hours).
- Start window: The time frame in which the backup job should start (e.g., between 1:00 AM – 3:00 AM).
- Completion window: The duration within which the backup job should complete.
{
“BackupRules”: [
{
“RuleName”: “DailyBackup”,
“TargetBackupVaultName”: “MyBackupVault”,
“ScheduleExpression”: “cron(0 1 * * ? *)”,
“StartWindowMinutes”: 120,
“CompletionWindowMinutes”: 360,
“RecoveryPointTags”: {“CreatedBy”: “AWSBackup”}
}
]
}
In the example above, a daily backup is scheduled to start at 1:00 AM UTC and has to start within a 2-hour window.
Retention Rule
The retention rule within a backup plan specifies how long backups should be kept. This duration may be from a few days for non-critical data to several years for archives or records that need to meet long-term retention requirements for compliance or other regulations.
{
“BackupRules”: [
{
“RuleName”: “DailyBackup”,
“TargetBackupVaultName”: “MyBackupVault”,
“ScheduleExpression”: “cron(0 1 * * ? *)”,
“StartWindowMinutes”: 120,
“CompletionWindowMinutes”: 360,
“RecoveryPointTags”: {“CreatedBy”: “AWSBackup”},
“RetentionDays”: 90
}
]
}
In this example, backups are retained for 90 days.
Backup Across AWS Services
AWS Backup supports multiple AWS services, allowing consistent backup practices across your AWS environment. Below is a comparison of how AWS Backup integrates with various AWS services:
AWS Service | Backup Capabilities |
---|---|
Amazon EBS | Backup of entire EBS volumes |
Amazon RDS | Automated backups, snapshots, and point-in-time recovery |
Amazon DynamoDB | Backup and restore tables |
Amazon EFS | Incremental backups for file systems |
AWS Storage Gateway | Backup of gateway-stored and gateway-cached volumes |
Each service’s integration with AWS Backup lends itself to different features and considerations, like the ability to perform incremental backups or specific restore mechanisms.
Example: AWS Backup across Multiple Services
Let’s consider a scenario where you have an application that uses Amazon EBS, Amazon RDS, and Amazon EFS. You can configure AWS Backup to manage backups for all these services within a single backup plan, setting different schedules and retention rules for each service, if needed.
AWS Backup’s centralized dashboard provides visibility into the backup and restore activities across services, ensuring compliance with the defined protection policies.
Conclusion
Setting up schedules and retention rules in AWS Backup helps in outlining a robust and reliable backup strategy that can be applied consistently across various AWS services. By defining backup plans and rules, organizations can streamline backup operations and meet their data protection goals, ensuring business continuity and compliance with regulatory standards.

Interview Questions
Can you explain how AWS Backup helps in centralizing and automating data protection across AWS services?
AWS Backup provides a centralized service to configure backup policies and automate the backup of data across various AWS services, such as Amazon EBS volumes, RDS databases, DynamoDB tables, EFS file systems, and Storage Gateway volumes. It simplifies backup management and enables users to meet their business and regulatory backup compliance requirements.
What is a backup plan in AWS Backup, and how do you configure one?
A backup plan in AWS Backup is a policy expression that defines when and how you want to back up your AWS resources. You configure it by defining a set of rules that include details such as the frequency of backups, the lifecycle of the backups (including retention periods), and the selection of resources by assigning resource tags.
What AWS services are supported by AWS Backup, and can you back up resources across regions?
AWS Backup supports Amazon EBS, RDS, DynamoDB, EFS, and AWS Storage Gateway. As of my knowledge cut-off date, AWS Backup does not support cross-region backup directly within the service, but you can copy snapshots across regions manually or via custom automation for some services like EBS.
How do you manage cross-account backup in AWS Backup?
Cross-account backup in AWS Backup is managed through AWS Backup’s cross-account management feature, which allows you to create and manage backups across multiple AWS accounts within your organization. You need to set up AWS Organizations and enable trusted access with AWS Backup.
How does AWS Backup handle the retention of backups, and what options do you have for setting retention policies?
AWS Backup handles the retention of backups through the use of backup plans that outline retention rules. Options for setting retention policies include defining the number of days, weeks, months, or years that you want to keep the backups. Once the retention period has passed, AWS Backup automatically deletes the backups.
How can you ensure your backup schedule complies with the 3-2-1 backup strategy?
To comply with the 3-2-1 backup strategy using AWS Backup, you would ensure that you have at least three total copies of your data (one primary and two backups), the backups are on two different media (this can include different storage systems or services within AWS), and one of the backups is kept offsite (which can be interpreted as either a different AWS region or using a hybrid cloud approach).
Can AWS Backup enforce compliance with regulatory requirements such as HIPAA or GDPR?
AWS Backup can help enforce compliance by ensuring that backup policies align with regulatory requirements. For instance, you can set specific retention periods and backup frequencies. However, AWS Backup itself is a tool, and compliance also depends on how these tools are used within an organization’s larger compliance framework.
Is it possible to automate the monitoring of backup activities and get notified in case of any failures?
Yes, it is possible to automate monitoring through AWS CloudWatch Events or AWS Backup events, which can trigger notifications in case of backup activity failures. These notifications can be sent via different channels using Amazon SNS.
How would you handle the backup of resources that are frequently updated, like a production DynamoDB table?
For resources like a DynamoDB table that are frequently updated, you would schedule more frequent backups to minimize data loss. Using AWS Backup, you can schedule backups every hour if needed and ensure that point-in-time recovery is enabled for DynamoDB.
How do you secure backups in AWS Backup to prevent unauthorized access and ensure data protection?
To secure backups in AWS Backup, encryption should be enabled for all backups using either AWS managed keys or customer managed keys in AWS KMS. Access to backups should be controlled using IAM policies and resource-based policies, with principles of least privilege applied. You should also regularly review permissions and enforce MFA for sensitive operations.
Can you describe how AWS Backup integrates with AWS Organizations for backup management?
AWS Backup integrates with AWS Organizations by allowing backup administrators to define and apply backup policies across their organization’s accounts. This ensures consistent backup practices are implemented enterprise-wide and simplifies backup governance for large organizations.
What would you consider when establishing a disaster recovery plan using AWS Backup?
When establishing a disaster recovery plan using AWS Backup, consider the recovery point objective (RPO) and recovery time objective (RTO) for each application, the criticality of the data, the frequency of backups, the geography of backup storage (ensuring it’s separate from production data), and the process for restoring backups in a disaster recovery scenario. It’s also important to regularly test your disaster recovery process to ensure it meets your organization’s requirements.
Remember that AWS keeps updating its services and features, so always consult the latest AWS documentation or AWS support for the most current information and best practices.
