AWS Backup now provides a streamlined experience for Amazon Elastic File System (EFS) Item-Level Recovery. You can now use AWS Backup to perform granular recovery of individual files or folders from Amazon EFS backups using a centralized console, for a simplified and fast restore experience, to meet more stringent Recovery Time Objective (RTO) requirements. To get started, choose the “Partial restore” restore type and provide one or more paths you want to recover using the AWS Backup console, SDK or CLI. This release is a continuation of our commitment to make data protection as streamlined and scalable as possible for our customers.
