How to backup server settings and users?

To retrieve list of users created and stored in the service, we recommend using the ListUsers API - https://docs.aws.amazon.com/transfer/latest/userguide/API_ListUsers.html. You can then use the output of this to create users on a new SFTP server via the CreateUsers API. Let us know if this will help meet your requirements for recreating your server for BC purposes.
