WhatsApp to Drive Backup Automation

I run WhatsApp Business from a single phone and need every file that passes through those chats—images, video, documents, voice notes, you name it—moved automatically to Google Drive. The transfer must happen reliably in the background and keep my Drive as tidy as possible: each sender or contact should get a dedicated folder, with their files tucked neatly inside. No manual taps, no jumbled directories. I’m looking for a lightweight, fully automated workflow that can: • Detect new inbound and outbound media on the phone’s WhatsApp Business installation. • Upload those files to Google Drive through the Drive API (or another secure method) without duplicates. • Create or reuse a top-level “WhatsApp Backup” directory, then nest sub-folders by contact name or number. • Preserve original filenames and timestamps so I can search later. • Log successes and any transfer failures so I can audit the process. Feel free to leverage Python, Google Apps Script, Android automation tools, or another proven stack—as long as the end result runs unattended and is straightforward for me to maintain. A brief setup guide and source code are part of the deliverables; clear in-line comments and a quick video walkthrough of the first run would be a plus. If you’ve previously automated WhatsApp exports, mobile file harvesting, or Drive folder structuring, show me. Solid experience with mobile device scripting, Drive quotas, and error-handling will make your proposal stand out.
