TLS for EFS mounts in 2 different regions on a single instance

Ok - just FYI for your roadmap, the reason I am trying to do this is cross-region backup for EFS. Its basically a custom implementation of AWS's recommended approach by using cloudformation to do cross-region EFS backups where it spins up an EC2 instance and copies between the EFS stores.

So you are saying that I am going to have to configure stunnel myself to get this working. I'll take a look at that github repo to see how hard it would be to add support for my use case first. Thanks for the info.

The EFS mount helper currently supports mounting EFS file systems located in the same region as your EC2 instance. Mounting file systems in other regions is not currently supported by the mount helper - please note that you are responsible for network charges when mounting EFS file systems across AWS regions.

Thanks for the feedback - we'll consider it as part of our roadmap. In the meanwhile, the mount helper is open-source (https://github.com/aws/efs-utils) if you'd like to submit a pull request to enable this functionality. The area of the code that defines region lookup is found here: https://github.com/aws/efs-utils/blob/master/src/mount_efs/init.py#L119
