    *   Manages communication with cloud storage providers (e.g., Google Drive, Dropbox)
    *   Handles authentication, upload/download, and metadata management

Performance considerations for Arq Backup include:

*   **Optimized Data Compression:** Using advanced algorithms to minimize data transfer sizes
*   **Asynchronous Transfer:** Utilizing asynchronous transfers to prevent data loss during backup operations
