As we have seen there are different options to backup data and create manual or automated snapshots in AWS services.

If we want to have lower RPO and RTO though, it might be necessary to have continuous replication.

This is available in many AWS services:

S3 cross-region replication

RDS cross-region replicas (created from snapshots)

Aurora Global Database ( low latency reads over multiple regions)

DynamoDB global tables

DocumentDB global clusters

Global datastore for Elasticache for Redis
