You accidentally deletes important data stored in an EFS file system. How can you recover the lost data?
You recover lost EFS data by restoring from an AWS Backup recovery point, using either a full restore or an item‑level restore, with all restored files placed in a special aws‑backup-restore_ directory* under the EFS root.
In short: AWS Backup is the supported mechanism for EFS data recovery. Restores are non‑destructive and always write recovered data into a new recovery directory rather than overwriting existing paths
