Backup Creation for EFS
- AWS Backup now supports Single File Restore for EFS.
- You can create backup by creating a backup plan, assigning it to EFS and then deploy it.
Refer below steps
Restoring Backup for EFS
- EFS file system restoration can be “Full restore” or through “Item-level restore” of the file system.
Full restore — it restores the filesystem in its entirety including all root level folders and files.
Item-level restore — you can select and restore up to 5 items within your Elastic File System. Enter a relative path to a file or folder.
- EFS Backup can be restored to the new EFS file system or to the source EFS file system using AWS Backup API, CLI, or AWS Console.
AWS Backup (Console)
i. Open the AWS Backup console.
ii. In the navigation pane, choose Protected resources. A list of your recovery points, including the resource type, is displayed by Resource Id. Choose a resource to open the Backups pane.
iii. To restore a resource, choose the radio button next to the recovery point in the Backups pane, and then choose Restore in the upper-right corner of the pane.
iv. Specify the restore parameters. Select restoration method by either:
a. Restore to a new file system.
b. Restore to directory in source file system.
v. For IAM role, choose Default role.
Note: If the AWS Backup default role is not present in your account, one will be created for you with the correct permissions.
vi. Choose Restore resource.
- You are brought to the restore jobs table, and you should see a message at the top of the page informing you about the restore job.
- The message also includes a link to the service console of the resource that you just restored.
- You can switch to that console and take action on the new resource that you created from the backup.
AWS Backup (CLI)
Amazon EFS Restore Metadata
- Use the following information to restore an Amazon Elastic File System (Amazon EFS) instance:
file-system-id — ID of the Amazon EFS file system that is backed up by AWS Backup. Returned in GetRecoveryPointRestoreMetadata.
Encrypted — A Boolean value that, if true, specifies that the file system is encrypted. If KmsKeyId is specified, Encrypted must be set to true.
KmsKeyId — Specifies the AWS KMS key that is used to encrypt the restored file system.
PerformanceMode — Specifies the throughput mode of the file system.
CreationToken — A user-supplied value that ensures the uniqueness (idempotency) of the request.
newFileSystem — A Boolean value that, if true, specifies that the recovery point is restored to a new Amazon EFS file system.
