# Enabling S3 Export for Existing Amazon DynamoDB Instances

Starting with Commvault Long-Term Support Release 11.40, Commvault uses S3 Export for DynamoDB backup and restore operations instead of the Scan API. DynamoDB instances created before 11.40 continue to use the Scan API.

You can enable the S3 export for the existing scan-based DynamoDB instances.

## Before You Begin

- Make sure that the instances are region specific.

- The DynamoDB tables should only be from one region.

- Add the required permissions for enabling S3 export. For information, see AWS DynamoDB Permissions JSON.

Note

Enabling S3 export is an irreversible process. Once enabled, you cannot disable it.

## Procedure

1. From the Command Center navigation pane, go to Protect > Databases.

   The database overview page appears.

2. On the Instances tab, from the list of Instances, select DynamoDB.

   The Instances page for cloud databases appears.

3. Click the DynamoDB instance for which you want to enable S3 Export.
