You are helping me build the following AI agent workflow.

## Goal
Notion Backup to Google Drive: Automatically backs up all Notion databases to Google Drive on a schedule and sends a confirmation or error alert via Telegram.

## Specification
- What it does: You get automatic backups of all your Notion databases saved securely in Google Drive on a set schedule without any manual work. You receive instant confirmation messages via Telegram when backups succeed or alerts immediately if any errors occur.
- Trigger: On a schedule (Scheduled · daily backup)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - n8n: Workflow orchestration and automation logic
  - Notion: Source of database content to backup
  - Google Drive: Destination storage for backup files
  - Telegram: Sending notification alerts upon completion

## Known pitfalls, handle each one explicitly in your implementation
1. Large Notion databases may exceed Google Drive upload size limits for single files so implement logic to split data into multiple smaller archives if necessary.
2. Telegram message formatting can break with special characters in error logs so sanitize the output string before sending the notification.

## Reference implementation
https://n8n.io/workflows/10235 (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.
