rsync for the cloud era, supporting 70+ storage backends. Rclone moves files between your machine and virtually any cloud storage — S3, Google Drive, Dropbox, Azure Blob, Backblaze B2, you name it — with a single consistent interface. If you work with multiple cloud providers, this is non-negotiable. The closest alternative is the vendor-specific CLIs (aws s3, gsutil, azcopy), but then you're learning three different tools. Cyberduck has a GUI but less scripting power. Restic handles backups specifically but doesn't do general file sync. Rclone does sync, copy, move, mount (FUSE), serve (WebDAV/HTTP/FTP), and encrypt — all from one binary. The mount feature alone is worth it: mount any cloud storage as a local directory. 56K+ GitHub stars and established-tier maturity mean it's not going anywhere. The catch: the configuration file stores credentials in plain text by default — encrypt it or lock down permissions. Performance varies wildly between backends. And the 70+ backends mean documentation is sprawling — finding the right flags for your specific provider takes digging.
