Restore AMI

Updated this week

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. Once an EC2 instance is backed up, you can choose to restore the AMIs across Accounts or Regions.

To restore an AMI:

  1. Log into your AWS Workloads (CloudRanger) console and navigate to Resources > EC2.

  2. 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.

Field

Description

Instance 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.

Region

The AWSRegion where the backed-up AMI is stored.

Availability Zone

Choose an availability zone within the region where the AMI is stored.
For more information, see Regions and Availability Zones

Instance Type

Choose 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.

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

Location

Account

Select the Druva CloudRanger Account to which the AMI is to be restored.

Region

Select the AWS Region to which the AMI is to be restored.

VPC
Subnet

Select a virtual private cloud (VPC) where you want the restored EC2 instance to run.
Select the subnet of the VPC where you want the restored EC2 instance to run.

Virtualization

Select the virtualization type for the restored EC2 instance.

Network Configuration

  • Automatically Assign a Private IP: Select this option to assign a default private IP address to the EC2 instance, which will be attached to it upon restore.

  • Specific Private IP: Specify the private IP address of the EC2 instance that will be attached to it upon restore. The IP address provided must be within the range of IP addresses for the Subnet specified previously.

  • Specific Elastic Network Interface: Select from the list of available preserved Elastic Network Interface (ENIs), and attach it to the newly restored EC2 instance, to ensure that network identity is retained. Selecting the ENI enables uninterrupted network continuity and ensures seamless restore of your EC2 instances.

📝 Notes

  • You can select ENIs based on the chosen Subnet and Availability Zone.

  • The number of ENIs and IPs per ENI depend on the instance type selected. Multiple ENI selection is currently not supported.

  • If selecting an Elastic Fabric Adapter (EFA-only option, this will not be used as the primary network interface, and is not supported on Windows.

  • The ENI retains associated security groups preserving the network-level security configuration.
    Do note that when specifying ENI as part of network configuration, the Security Groups option will remain disabled.
