Overview

Snapshots are incremental backups, which means that only the data blocks that have changed since your most recent snapshot will be backed-up. Upon restoring a snapshot, the entire point in time copy is restored. When you delete a snapshot, only the data exclusive to that snapshot is eliminated.

You can choose one of the following approaches to restore an EBS snapshot:

• Restore as an instance
• Restore to a volume
• Request a file-level restore

Restoring EBS Snapshots as an Instance

Druva CloudRanger boots up an EC2 instance using predefined parameters and then attaches the snapshots to be restored as a volume to that instance.

To restore a snapshot as an instance:

1. .Log into your Druva CloudRanger console and navigate to Resources > EBS.
   
   
    
2. Navigate to the Backups tab and select the snapshot that you wish to restore.
3. On the backup details page, click Restore.

   Note: Alternatively, you may select the snapshot from the Backup page, and then click Restore to initiate the restore process.

   On the Restore dialog, select the restore type you wish to proceed with. The File Level Recovery option is selected by default.
   
   

4. Select the Restore as an Instance option to launch an instance from the snapshot.
   The Restore as an instance page displays an overview of the instance, the snapshot Location & Security, as well as the associated Tags.
   
   

5. The latest available instance settings are pre-populated. Click  to modify the settings based on your business requirements:

   Field	Description
   General
   Name	By default, Druva CloudRanger displays the name of the original EC2 instance, and if unavailable, the instance ID is used as the name.  You can choose to modify the default instance name.
   Architecture	Select the processor architecture for the instance, for example, i386.
   Instance Type	Select an instance type of the restored EC2 instance. By default, Druva CloudRanger selects the original EC2 instance type. Note: Not all instance types are supported in all regions. If you run into issues with the restore, verify that the selected instances are supported for that region. For more information, refer to the AWS documentation.
   Image ID	The ID of the associated AMI.
   Block Device Mappings	The Device Name and ID of the snapshot to be restored. Use the  and  icons to add or delete new devices and snapshot IDs.

6. Click Next.

8. Click Next.
