rclone

A command‑line program enables copying, moving, and synchronizing files and directories between local storage and a wide range of cloud services. It supports operations such as one‑way sync, two‑way sync, and copy, mirroring the behavior of traditional file‑transfer tools while handling remote endpoints.

The tool is aimed at system administrators, DevOps engineers, and developers who need to automate data transfer across many providers, including Amazon S3, Google Drive, Dropbox, Backblaze B2, FTP, WebDAV, and numerous other storage platforms. Its CLI interface allows scripting and integration into existing workflows without a graphical front end.

What distinguishes it is the extensive list of supported back‑ends, unified command syntax, and stable, mature implementation that has been packaged for direct download and Docker use. The project provides documentation, build status badges, and a community forum for support.
