EFS Backup Solution v1.2 Released

The EFS-to-EFS backup solution automatically deploys the necessary AWS services, including Amazon CloudWatch and AWS Lambda, to create automated, incremental backups of Amazon EFS file systems on a customer-defined schedule. The solution is simple to configure and makes it easier to create and restore backups for data recovery and protection. You can use this solution to create backups for your file system(s) on a daily, weekly, or monthly basis and retain these backups as necessary to meet your business requirements.

Changes with v1.2:

  • fixed timeout issue with custom lambda resource fetching latest AMI
  • removed duplicate line in efs-to-efs-backup.template
  • error handling for efs mount targets not mounted
  • fixed false notification when efs mount targets not mounted
  • added support for restoring sub directory from the backup
  • backup window provided in form of drop down menu to avoid input errors
  • parallelized removal of snapshot in
  • improved overall backup and restore experience

Open source mount helper for Amazon Elastic File System

At the AWS Summit in San Francisco, we announced the availability of encryption of data in transit for Amazon Elastic File System (EFS). With this launch, customers can now easily encrypt all network traffic between their file systems and clients. EFS uses the industry-standard Transport Layer Security protocol (TLS) version 1.2 to encrypt data in transit. To enable this feature and further simplify the experience of using EFS, we also launched a new, open-source EFS mount helper, available in Amazon Linux and Amazon Linux 2 AMIs, and hosted as an open-source project on the AWS GitHub page.
