AWS has a service called Storage Gateway. One of the gateways supported by Storage Gateway is a File Gateway. You can find more information about this in the relevant AWS docs - https://aws.amazon.com/storagegateway/file/
The file gateway can be used to not only move files from your on-prem to Amazon S3 and Amazon FSx for Windows File Servers on AWS but also make those files accessible for your on-prem users.
This blog https://aws.amazon.com/blogs/storage/aws-storage-gateway-in-2021-year-in-review/ also has information on this.
