Cloud Sync Health Monitor: Diagnose and fix file synchronization issues.

The user's severe frustration with OneDrive taking '50 hours to look for changes' and then failing to sync despite showing 'Up to date' points to a critical pain point: the unreliability and opaqueness of cloud sync services, especially with large or long-dormant datasets. A SaaS solution could be a 'Cloud Sync Health Monitor & Optimizer.' This tool would act as an independent diagnostic and management layer on top of existing cloud storage services (OneDrive, Dropbox, Google Drive, Box). It would provide detailed, real-time sync status, error logging in a human-readable format, proactive alerts for impending issues (e.g., stuck syncs, conflicts, low storage), and intelligent troubleshooting recommendations. Features could include bandwidth monitoring, selective sync control beyond native clients, and data integrity checks. The product form would be a desktop client with a web-based dashboard for advanced monitoring. The revenue model would be subscription-based, tiered by the number of cloud accounts/devices connected, data volume, and premium features. Expected ARR could be $50K-$300K+ by targeting power users, small businesses, and remote teams heavily reliant on cloud storage who are constantly battling sync issues.
