If you’re not aware of AWS Backup Service, I’d suggest you to read What is AWS Backup? before going through the FAQ.

  • AWS Backup is a centralized backup service that makes it easy and cost-effective for you to back up your application data across AWS services in the AWS Cloud and on premises, helping you meet your business and regulatory backup compliance requirements

  • Today, several AWS services offer backup features that help you protect your data, such as EBS snapshots, RDS snapshots, DynamoDB backups, and Storage Gateway snapshots. All existing per-service backup capabilities remain unchanged.

  • For AWS services that have backup functionality built on AWS Backup, such as Amazon EFS, AWS Backup provides you with backup management capabilities, such as backup scheduling, retention management and backup monitoring, as well as additional features, such as lifecycling backups to a low-cost storage tier, backup storage and encryption that is independent from its source data, and backup access policies.

  • To get started with AWS Backup, create a backup policy called a backup plan, which defines parameters such as how frequently to back up your resources and how long to store those backups.

  • You can use AWS Backup to manage the backups of EBS volumes, RDS databases, DynamoDB tables, EFS file systems, and Storage Gateway volumes.

  • AWS Backup integrates with Storage Gateway to enable you to back up your on-premises Storage Gateway volumes, providing a common way to manage the backups of your application data both on premises and in the AWS cloud.

  • Amazon Data Lifecycle Management (DLM) policies and backup plans created in AWS Backup work independently from each other and provide two ways to manage EBS snapshots. DLM provides a simple way to manage the lifecycle of EBS resources, such as volume snapshots. Use DLM when you want to automate the creation, retention, and deletion of EBS snapshots. You should use AWS Backup to manage and monitor backups across the AWS services you use, including EBS volumes, from a single place.

  • A recovery point represents the content of a resource at a specified time. Recovery points also include metadata such as information about the resource, restore parameters, and tags.

  • Each backup rule is composed of 1) a backup schedule, which includes the backup frequency (Recovery Point Objective - RPO) and backup window, 2) a lifecycle rule that specifies when to transition a backup from one storage tier to another and when to expire the recovery point, 3) the Backup Vault in which to place the created recovery points in, and 4) the tags to be added to backups upon creation.

  • A Backup Vault is a logical backup container for your recovery points that allows you to organize your backups

  • For AWS services that introduce backup functionality built on AWS Backup, such as Amazon EFS, AWS Backup provides a lifecycle feature that allows you to automatically transition your recovery points from a warm storage tier backed by Amazon S3 that provides millisecond access time to your backups to a lower-cost cold storage tier backed by Glacier that provides a restore time of 3-5 hours.
