Backup plans

In Amazon Backup, a backup plan is a policy expression that defines when and how you want to back up your Amazon resources, such as Amazon DynamoDB tables or Amazon Elastic File System (Amazon EFS) file systems. You can assign resources to backup plans, and Amazon Backup automatically backs up and retains backups for those resources according to the backup plan. You can create multiple backup plans if you have workloads with different backup requirements. By default, backup windows are optimized by Amazon Backup. You can customize the backup window in the console or programmatically.

Amazon Backup efficiently stores your periodic backups incrementally. The first backup of an Amazon resource backs up a full copy of your data. For each successive incremental backup, only the changes to your Amazon resources are backed up. Incremental backups enable you to benefit from the data protection of frequent backups while minimizing storage costs.

Amazon Backup also seamlessly manages your backup plan's lifecycle based on your retention settings, which allows you to restore when needed.
