You might look at File Gateway. You can setup specific times for sync and it does the sync to S3 via an encrypted means. You can then use an S3 storage rule to archive to Glacier. Maybe on-prem, you could use rsync or some other tool to sync the NFS share over to the NFS share published on the File Gateway or maybe just replace the NFS share with the File Gateway share directly.
You can read about it here: https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.html
