Backup sets for Amazon EFS define the File Systems to be backed up, backup schedule, and so on.
Before you begin
Ensure the following before you configure your Amazon Elastic File Systems for backup:
Prerequisites: Verify access to your AWS environment:
Configure Amazon EFS Mount Target
Network connectivity prerequisites
Druva Quantum Bridge deployment
📝 Note: Druva provisions Druva Quantum Bridge in the same VPC and subnet as your EFS mount target. This ensures connectivity and avoids cross-AZ data transfer costs.EFS File System Policy configuration
Discovery: Automatic discovery of your EFS file systems with periodic sync.
Storage Rules: Configure Storage Rules to map the cloud Storage with the AWS Region in which the EFS file systems reside.
Configure backup sets
To configure backup sets:
Log in to the AWS Workloads Management Console.
Click EFS on the left pane and navigate to the All File Systems page.
Select a File System and click Configure for Backup.
On the Backup Settings tab, specify a Backup Set Name.
Under Policy Settings, specify the backup policy to apply to the backup set.
You can attach an existing Backup Policy when configuring a backup set.
Alternatively, select New Backup Policy and proceed with creating a custom policy for the backup set.
Click Next.
On the Backup Content tab, provide the following information.
Note: Under File Selection, you can specify the filter criteria to identify specific File Systems to include or exclude from the backup set.
Field | Description |
Folder Selection |
|
Backup All Folders | Select to backup all folders within the selected Amazon Elastic File System. |
Backup Specific Folders | When configuring a File System for backup, you have the option to only select specific folders. For example: When prefixes are specified, only the data within those exact prefixes will be backed up. If none of the specified prefixes are found, the backup job will fail. If some but not all of the specified prefixes are found, the prefixes that were not found will be noted in the progress logs. |
Exclude Subfolders | Select the subfolders to be excluded from the backup. Based on the selected file types, all such extensions are pre-filled in the Exclude File Extensions field. |
File Selection |
|
Enable File inclusion/exclusions | You can configure specific file systems for backup based on specific include and exclude criteria. |
Exclude Files | Select this option to exclude specific File Systems from the backup configuration. Once enabled you can view Exclude by File Categories and Exclude File Extensions options. For instance, excluding high-churn, low-value directories reduces backup size and duration. |
Exclude by File Categories | Specify the Amazon File System categories to be excluded from the backup set. Note: Exclude rules take precedence when the same resource is matched based on the include and exclude criteria selected. |
Exclude File Extensions | Specify the file extensions that need to be excluded in the backup set. |
File Name Patterns | Enter file name patterns that must be excluded from or included in the backup of folders specified under Backup Content. File patterns start with a * and can contain * *.string* or * .*string in the pattern string. Enter patterns like *.ext in the format ext in the file extension field under File Types. 📝 Note The filename patterns File* and File*.extension are unsupported. For example, do not use a filename pattern like i mg* to include/exclude all files that start with img. Use *img* instead. Do not use a filename pattern like i mg*.jpg to include/exclude all files that end with the extension jpg. Enter the file extension jpg under File Types instead. |
Include Only following files | Select this option to exclude specific File Systems from the backup configuration. Once enabled you can view Include by File Categories and Include File Extensions options. |
Include File Categories | Select this option to include specific File Systems as part of the backup set configuration. Once enabled you can view Include by File Categories and Include File Extensions options. |
Include File Extensions | Specify the file extensions that need to be included in the backup set. |

The backup set is created, and rules are configured.
Edit backup sets
Log in to the AWS Workloads Management Console and click EFS on the left pane.
Navigate to the Backup Sets tab.
This page lists all the backup sets configured for the EFS resource.Select the backup set to be modified, and then click Edit.
Alternatively, select the backup set and click Edit on the backup set Details page.
You can also modify the backup set from the configured Amazon EFS resource details page.
Log in to the AWS Workloads Management Console.
Click EFS on the left pane and navigate to the All File Systems page. Select an Amazon Elastic File System.
On the configured Backup Sets section, select the backup set that needs to be disabled, click more options, and then click Edit.
Disable Amazon EFS backups
Disable Backup to pause automatic backups from a specific backup set. Your backup settings remain unaffected, and can be applied whenever the backup is enabled for the backup set. You can disable backups for non-critical data or to prevent automatic backup of corrupt or infected files.
Proceed with one of the following ways to disable backup:
Log in to the AWS Workloads Management Console and click EFS on the left pane.
Navigate to the Backup Sets tab.
Select one or more backup sets to be disabled. Click more options, and then click Disable Backup.
Alternatively, select the backup set and click Edit on the backup set Details page.
You can also disable backups from the configured Amazon EFS resource details page.
Log in to the AWS Workloads Management Console.
Click EFS on the left pane and navigate to the All File Systems page. Select an Amazon Elastic File System.
On the configured Backup Sets section, select the backup set that needs to be disabled, click more options, and then click Disable Backup.
📝 Note
All backups for the selected Amazon Elastic File System remain disabled until they are enabled again using the Enable Backup option.
Delete backup sets
Deleting backup sets is essential when you plan to delete an Amazon Elastic File System from your management console.
When you delete a backup set:
The backup policy which was linked with the backup set is detached.
The backups occurring through the backup set are stopped.
The snapshots backed up using the backup set are deleted.
📝 Note
To preserve the Amazon EFS data, you can restore backups and then proceed with the deletion of backup sets.
The retention period is not honored for the most recent snapshot when backups for an Amazon EFS resource is disabled. This allows you to restore the latest backup at a later point, if required.
To delete a backup set:
Log in to the AWS Workloads Management Console and click EFS on the left pane.
Navigate to the Backup Sets tab, and select the backup set to be deleted.
From the Summary page, click more options in the top right corner, and select Delete.
A confirmation dialog displays. To prevent accidental data loss, you are required to provide the Reason for deletion. You must enter a reason to proceed (character limit: minimum of 10 characters and a maximum of 150 characters). All deletion requests and associated reasons are logged in the Audit Trails for security and compliance. For more information, see View Admin Audit Trails page.
Delete Amazon EFS recovery points
If you are a cloud administrator, you can delete warm recovery points of Amazon Elastic File Systems that you no longer require.
Once you delete a recovery point, Druva purges the recovery point data from the warm storage, thus freeing up the storage space.
📝 Note
You cannot delete the most-recent recovery points of an Amazon EFS resource. However, all recovery points get compacted according to the retention period defined in the backup policy.
To delete a recovery point:
Log in to the AWS Workloads Management Console and click EFS on the left pane.
Navigate to the Backup Sets tab, and select a backup set.
The Recovery Points tab lists all the recovery points for this backup set. You can filter the recovery points by Recovery point Type (Hot, Warm, or Cold), and Created In ( Last 24 hours, Last 7 days, and Last 1 month ). Click the Filters icon to filter the displayed recovery points.
Select a recovery point that you want to delete, and then click Delete. This deletes the recovery point from the storage and frees up space.
📝 Note
The most recent recovery point of a backup set cannot be deleted. However, all recovery points get compacted according to the retention period defined in the backup policy.
Recover critical backups from accidental deletion with Rollback Actions
Disabling an Amazon EFS backup configuration deletes the backup set and all corresponding recovery points. However, if you have the Rollback Actions feature enabled, you can recover the deleted recovery points within a configurable rollback window.
Once configured, the deleted recovery points will remain available for rollback for a specific period, post which they are permanently deleted. Administrators can revert malicious or unintended deletes without any loss of data. If your Amazon EFS recovery points have been intentionally removed, the backup copies will be permanently deleted post the rollback window, and these Elastic File Systems can then be reconfigured for backup. For more information, see Rollback Actions.
📝 Note
To configure Rollback Actions, you will need the Security Essentials license. To activate the license, contact Support.
