Restore an AMI

Overview

This article explains how to restore AMIs.

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, Druva CloudRanger stores them in the region specified in the backup policy.

Restoring an AMI

To restore an AMI:

  1. Log into your Druva CloudRanger console and navigate to Backups.

    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 AWS Region 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.
