Working with the official AWS S3 CLI, as well tools like s5cmd I quickly realized they aren’t optimized for resource constrained systems, rather more towards uploading as fast as possible and in parallel. This is great for most use cases, but not when you want to minimize the impact on the system, like during frequent backup operations and on a system with half a gig of memory for example.

I dusted off my Go tools and build a simple tool to serve this purpose. Say hello to tinyups3 – streaming S3 uploader optimized for minimum CPU and RAM usage. It’s a single binary, open sourced under the MIT license.

Head over to GitHub for installation and usage instructions.

Happy uploading!
