Command-line tool for syncing, backing up, and managing files on cloud storage services like Google Drive, S3, Dropbox, Azure, and many others with checksums and encryption.

Rclone is a powerful command-line program that manages files across cloud storage platforms with the efficiency and familiarity of Unix tools. It supports over 150 cloud providers including Google Drive, Amazon S3, Dropbox, Microsoft Azure, Box, and many others, plus standard protocols like WebDAV and FTP.

The tool functions as the Swiss army knife of cloud storage, offering cloud equivalents to Unix commands like rsync, cp, mv, mount, and ls. Key capabilities include:

Reliable transfers - MD5 and SHA1 hashes verify file integrity at all times, timestamps are preserved, and operations can restart from the last successful file
Flexible syncing - One-way mirroring to make directories identical, two-way bidirectional sync, or move files with local deletion after verification
Data protection - Encrypt files before uploading, check hashes for missing or extra files, and perform server-side transfers to minimize bandwidth
Virtual filesystems - Mount cloud storage as network disks on Windows, macOS, Linux, and FreeBSD; serve storage over HTTP, WebDAV, SFTP, and S3
Advanced features - Multi-threaded downloads, bandwidth throttling, quota management, and combining multiple storage providers into unified directories

Rclone excels at backup and restore operations, cloud migration between providers, data analysis, and complex file management workflows. The mature open-source project, written in Go, includes official packages for Ubuntu, Debian, Fedora, Brew, and Chocolatey. Its active community supports diverse use cases from personal backups to enterprise data solutions.
