A company stores and manages documents in an Amazon Elastic File System (Amazon EFS) file system. The file system is encrypted with an AWS Key Management Service (AWS KMS) key. The file system is mounted to an Amazon EC2 instance that runs proprietary software. The company has enabled automatic backups for the file system. The automatic backups use the AWS Backup default backup plan. A solutions architect must ensure that deleted documents can be recovered within an RPO of 100 minutes. Which solution will meet these requirements?
