Dynamo DB: How to achieve 1 Min RTO/2 Minute RPO for Disaster Recovery?

DynamoDB how to achieve 1 minute RTO vs < 2 minute RPO?

if we need to design a solution for disaster recovery for the above RTO/RPO requirements – which would suffice? I’m tempted to say (C) but PITR is 5 minutes (but global tables RPO is 1 second so how does PITR even come into the picture?). If (C) is incorrect – what would be the choice? A or D?

• A. Create a DynamoDB stream that is processed by an AWS Lambda function that copies the data to a DynamoDB table in another Region.

• B. Use a DynamoDB global table replica in another Region. Enable point-in-time recovery for both tables.

• C. Use a DynamoDB Accelerator table in another Region. Enable point-in-time recovery for the table.

• D. Create an AWS Backup plan and assign the DynamoDB table as a resource.

Hi SalientListener,

Thanks for posting your question. I’m unsure where you got this question. However, if you enrolled for the course, you should find a thorough explanation on this. I would say:

RTO – focus on features that help on availability

RPO – focus on features that address recovery.

I hope this helps.
