You are helping me build the following AI agent workflow.

## Goal
FTP to Google Drive File Backup: Scheduled sync pulls new files from an FTP server and uploads them to a specified Google Drive folder for automated backup.

## Specification
- What it does: You get reliable, automated backups of your FTP server files directly into a specific Google Drive folder on a scheduled basis. This hands-free process continuously monitors the source directory to download new items, ensuring your data is safely stored in the cloud without any manual intervention.
- Trigger: On a schedule (Scheduled · every hour)
- Autonomy: Fully hands-off
- Expected setup effort: under an hour
- Tools/services involved:
  - FTP: List and download files from server
  - Google Drive: Upload and store backup files

## Known pitfalls, handle each one explicitly in your implementation
1. FTP transfers are unencrypted so you should use FTPS or SFTP if the data contains sensitive information to avoid interception risks.
2. File permissions might not transfer correctly from FTP to Drive so explicitly set the desired ownership or visibility flags on the uploaded files.

## Reference implementation
https://n8n.io/workflows/7604 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
