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:

Restore as an instance
Restore to a volume

File Level Search and File Level Restore are currently not supported directly from Druva Cloud. You will first have to restore the AMI snapshot and then proceed with File Level Search on the new snapshot.

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:

Log into your Druva CloudRanger console and navigate to Resources > EBS.
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.

4. On the Restore dialog, 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 to modify the settings based on your business requirements:

Field	Description
General
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. Use the and icons to add or delete new devices and snapshot IDs.
Association
Backup	The associated snapshot name.
Resource	By default, this is the name of the original EC2 instance, and if unavailable, the instance ID is used as the name.
Associate As	Select A Copy of if the associated resource is a replica of the original instance. Select A Replacement of if the associated resource is a replacement of the original instance. If you select this option, you may choose to: *Add to the same backup policy of original resource: Select this option to add the restored instance to the original backup policy so it continues to be backed up based on the existing policy schedule. Move backups from* the original to the replaced instance: Selecting this option allows you to move the existing backups to the replacement so they continue to be listed under the new instance.

Click Next.
Review the Location & Security settings that are pre-populated. Click to modify the settings, as applicable:

Field	Description
Location
Account	The Druva CloudRanger Account that the backed-up snapshot is associated with.
Region	The AWS Region where the backed-up snapshot is stored.
VPC	A virtual private cloud (VPC) where you want the restored EC2 instance to run.
Subnet	Subnet of the VPC where you want the restored EC2 instance to run.
Virtualization	Virtualization type for the restored EC2 instance.
Security
Key Name	The backup encryption target key for the EC2 instance. If you plan on remotely connecting to the restored EC2 instance, select a key pair created in your account.
Instance Profile	Instance profile for the restored EC2 instance.
Security Groups	Security group for the restored EC2 instance.

Click Next
Review the instance Tags. Tags act as metadata to help identify and organize your AWS resources.
Click 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

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.

Note: When restoring a volume from an EBS snapshot, Druva CloudRanger restores the volume disk signature.

However, if the original disk is attached to the EC2 instance. mounting a restored volume as an additional disk may trigger an error. In such cases, AWS detects a conflict due to duplicate disk signatures when attempting to mount volumes using the same disk signature. The restored disk then appears as invalid on the OS of the EC2 Instance.

As a workaround, mount the restored volume to another EC2 Instance to access the data.

To restore a snapshot to a volume:

Log into your Druva CloudRanger console and navigate to Resources > EBS.
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.

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 as a volume option.

You may modify the volume settings and Tags based on your business requirements:

Field	Description
Account	The Druva CloudRanger Account that the backed-up snapshot is associated with.
Region	The AWS Region where the backed-up snapshot is stored.
Volume Name	Specify a name for the volume (mandatory).
Volume Size	The volume size in GB. The value here must be greater than or equal to the backup data size of the snapshot.
Volume Type	Volume type, for example General Purpose SSD. For more information, see Amazon EBS Volume Types.
Tags
Key	This section displays the tag keys that have been specified for the source EC2 instance or the AMI. Tags act as metadata to help identify and organize your AWS resources.
Value	The Value will depend on the Key specified. Key: Created by Policy; Value: New Key: Origin; Value: Origin ID

Click Finish.

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