Amazon EC2 enables replacing root volumes for quick restoration and troubleshooting
Amazon EC2 announces the Replace Root Volume feature that enables customers to replace the root volume for a running instance. The feature restores the root volume of an instance to its launch state, or to a specific snapshot, without stopping the instance. This allows customers to fix issues, such as root volume corruption or guest operating system network configuration errors, while retaining the instance store data, networking and IAM configuration.

The feature restores the root volume of an instance to its launch state, or to a specific snapshot, without stopping the instance. This allows customers to fix issues, such as root volume corruption or guest operating system network configuration errors, while retaining the instance store data, networking and IAM configuration.
Customers can use the feature to restore the root volume to the last known good snapshot and resume operations with their instance store data intact. For example, customers with Big Data workloads can use the Replace Root Volume feature to quickly restore their instance and avoid instance store data replication.
The Replace Root Volume feature is available in all public AWS Regions and AWS GovCloud (US) Regions. To learn more about the Replace Root Volume feature, visit the Replace a root volume page.
