Druva Documentation

Restoring EBS snapshots

Provides information on restoring EBS snapshots.

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 a snapshot from Druva Cloud:

Restoring 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.

Note: Set the Location filter to Druva Cloud to view all backups on Druva Cloud.

3. On the backup details page, click Restore. Alternatively, select the snapshot from the Backup page, and then click Restore.

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.

The latest available instance settings are pre-populated. Click clipboard_e597bd7adf5af0aac066207ea3fd3f46a.png to modify the settings based on your business requirements:

Field

Description

Image ID

The ID of the associated AMI.

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.

Block Device Mappings

The Device Name and ID of the Snapshot to be restored.

  1. Click Next
  2. Review the instance Tags. Tags act as metadata to help identify and organize your AWS resources.
    Click clipboard_e597bd7adf5af0aac066207ea3fd3f46a.png to assign new key:value pairs to the restored instance:
  • Key: This section displays the tag keys that have been specified for the source EC2 instance or the AMI.
  • Value: The Value will depend on the Key specified.
    Key: Created by Policy; Value: New
    Key: Origin; Value: Origin ID
  1. Click Finish.

The restored snapshot volumes will now be available on the Restores page.

Restoring Snapshots to a Volume

Druva CloudRanger allows you can restore a snapshot to a new unattached EBS volume, in an Availability Zone of your choice.

To restore a snapshot to a volume:

  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.
