rclone

File synchronization with rclone keeps local directories and cloud remotes in sync by comparing files and transferring only changes. Configure rclone with your cloud credentials, then use `rclone sync` to mirror folders bidirectionally or one-way, automating backups and redundancy across S3, Google Drive, Dropbox, and other supported backends.

Rclone supports 150+ cloud backends including S3, Google Drive, Dropbox, OneDrive, Azure Blob Storage, and many others. You configure each remote with credentials via `rclone config`, then upload or sync files to any configured destination, enabling multi-cloud backup strategies and cross-platform file management.

Rclone must be installed on your system independently; this Skill provides workflows and scripts to use it. The setup checker script verifies your rclone installation and remote configurations are ready before running upload, sync, and check operations.

Yes. Configure multiple remotes in rclone, then run separate `rclone sync` commands or scripts to replicate your project directory to S3, Google Drive, and other destinations simultaneously, creating redundant backups across different cloud providers in a single workflow.

Use `rclone check` to verify file integrity between source and destination, review rclone logs for permission or connection errors, and confirm remote credentials are valid via `rclone config`. The setup checker script also diagnoses common installation and configuration issues before operations run.

Rclone stores encrypted credentials in its config file after you run `rclone config` interactively. Store the config in a secure location, use environment variables for sensitive values if needed, and restrict file permissions to prevent unauthorized access to your cloud authentication data.
