About Data Gateway
If you want to choose Object Storage replication mode for migration of your assets to AWS, you need to deploy a Data Gateway in AWS environment.
The Data Gateway acts like a communication channel between the on-premises Replication Gateway and cloud Replication Gateway. The data being replicated from the on-premises data center gets compressed and stored in S3 bucket in the form of objects. The cloud Replication Gateway pulls this data from S3 bucket, decompresses it and applies to the target disk.
You can use a single Data Gateway for replicating data between multiple Replication Gateways.
To deploy the Data Gateway in AWS, you need to download a zip file that is shipped along with Veritas Resiliency Platform.
See Deploying the Data Gateway in AWS.
A few resources get created in AWS when you deploy a Data Gateway in the AWS environment. You must not delete these resources while the Data Gateway is in use as it may impact the functionality of the feature and the product. These resources automatically get deleted when you delete the Data Gateway.
