Architecture

Overview

This PowerShell script provides bidirectional asset synchronization between Google Drive and local machine using rclone's bisync feature. It's designed for team collaboration with shared service account authentication.

Why This Exists

• GitHub LFS Cost: Too expensive for large projects (1GB free storage)
• Bidirectional Sync: One-way sync doesn't work when multiple people make changes
• Conflict Resolution: Bisync handles changes from both sides intelligently

Security Model

• Each user authenticates with their own Google account
• Drive folder is shared via Google Drive's sharing feature
• Never share your rclone.conf file with others
• Service account credentials are placed manually in .rclone/service-account.json

Key Components

• sync-assets.ps1: Main sync script
• .env: Project-specific configuration
• .rclone/rclone.conf: Shared rclone configuration
• .rclone/service-account.json: Service account credentials (gitignored)
