Announcing automatic backups for Amazon Elastic File System
Starting today, all new file systems created using the Amazon Elastic File System (Amazon EFS) console are automatically backed up with AWS Backup using the recommended settings (daily backups with a retention of 35 days). Automatic backups for Amazon EFS further simplifies backup management of your file systems by easily enabling you to meet your business and regulatory backup compliance requirements. It is now as easy as checking a check box in the Amazon EFS console, or making a single API call, to enable backups for your existing file systems. You can also disable automatic backups for your file systems at any time.
