[Hey Arun! There's no Active-Active at the EBS level. You can set up EFS with cross-region replication, but it won't work well for an Active-Active configuration. If you can, I'd save the data to Aurora Global or DynamoDB Global Table, with an RPO of 1 second. Anything lower than 1 second will be REALLY hard to do, and probably not worth the effort.](https://hashnode.com/posts/automating-ebs-snapshots-for-disaster-recovery-guide/639cfad429d4a06a6e6ed2d3/comment/650c74896e010e234b1d00bb#reply-651dd879693e2fa4bb060c6d)
