What is rclone?

Rclone is a free command-line tool that helps you move, copy, and synchronize files across different cloud storage services. Think of it as a universal translator for your files: instead of manually logging into Google Drive, Dropbox, Amazon S3, or OneDrive to move data around, you use this single tool to manage them all from your computer's terminal. It works with a remarkably long list of providers, covering everything from major consumer services to specialized enterprise storage. At a high level, the tool works by treating every storage location, whether it is a folder on your local computer or a bucket in a remote cloud service, as just another directory. Once you connect your accounts, you can tell it to copy files from one place to another, or to "sync" them so that a destination folder becomes an exact mirror of the source. The tool checks file integrity along the way using checksums, so you can be confident your files arrived without corruption. Who would use this? A founder migrating a startup's archives from Dropbox to a cheaper service like Backblaze B2 could use it to transfer everything in one go. A product manager who needs an automated, nightly backup of their team's shared Google Drive could set it up to copy new files to a local office server. It is also incredibly useful for anyone who wants to consolidate data scattered across multiple personal accounts into one central location, all without uploading or downloading files manually through a web browser. Beyond simple copying, the project includes several powerful features. It can optionally encrypt your files before they reach the cloud, meaning even if the storage provider is compromised, your data remains unreadable. It can also break large files into smaller chunks for easier uploading, compress files to save space, or even mount a cloud storage account as if it were a local hard drive on your computer. You can also use it to serve files from a cloud account over the internet to other devices.
