Overview
An Amazon Machine Image (AMI) is a template that contains a software configuration (for example, an operating system, an application server, and applications). From an AMI, you can launch an instance, which is a copy of the AMI running as a virtual server in the cloud. For example, the AMI is an image of your EC2 instance. You can restore an EC2 instance backed up to Druva Cloud from the storage region specified in the backup policy.
Restoring AMIs
To restore an AMI:
Log into your management console and navigate to Resources > EC2.
Navigate to the Backups tab and select the AMI that you wish to restore.
On the backup details page, click Restore.
Alternatively, you may select the AMI from the Backups page, and then click Restore to initiate the restore process.

Restoring AMIs with File Level Recovery
With the file-level recovery functionality, you can initiate a recovery instance within Druva’s environment and choose the files you want to recover.
This launches an instance and runs Druva's FLR agent, which virtually mounts the chosen point-in-time backup and serves a browsable view of files/folders to restore. Upon initiating a restore, the FLR instance zips the selected files into a single zip archive, which are accessible via the S3 bucket in your source AWS account.
Before you begin
To enable this feature, you will need to update your AWS Access Role by deploying the latest CloudFormation template for each account in which you intend to leverage file level recovery. For more information, see Update Existing AWS Access Roles in Druva CloudRanger.
Procedure
To initiate a file-level recovery:
Log into your management console and navigate to Resources > EC2.
Navigate to the Backups tab and select the AMI that you wish to restore.
Note: Set the Location filter to Druva Cloud to view all backups on Druva Cloud.On the backup details page, click Restore. Alternatively, select the snapshot from the Backup page, and then click Restore.
On the Restore dialog, select File level recovery.
📝Note
The restore once initiated launches an instance in Druva’s managed infrastructure.
5. Navigate to the browse view presented and select the file(s) to be restored.
📝Note
Once initiated, the instance is created only with the selected files and folders, and the instance is discarded after 2 hours.
6. Navigate to your Jobs Restore page to track the restore job.
7. A link to the restored files is presented on the Restores page, which will redirect you to the file location within the S3 bucket of your AWS account.
Once the instance becomes available, locate the archived files for downloading. You may also download a directory with one click using the download icons on the right, which will download the archive with a .zip extension.
