AWS has recently released File Mover Express, an open-source application under the Apache 2.0 license for transferring large files between local systems and Amazon S3. Available for macOS, Windows, and Linux, it supports parallel transfers, automatic performance tuning, retries, pause and resume, and file integrity verification.
Designed to “move media to S3 at wire speed,” File Mover Express supports auto-tuned parallel transfers, pause and resume, a desktop GUI, a scriptable CLI, and automatic uploads from monitored folders.
