+# Archive: Task 65132 - n8n Workflows Git Versioning
+
+## Task Overview
+**Redmine Issue**: #65132  
+**Title**: Save n8n workflows to git repository for version control and deployment  
+**Completion Date**: 2025-08-10  
+**Implementation Time**: ~3 hours (including code review improvements)  
+**Complexity**: Level 3 → Simplified to Level 1 → Enhanced to Enterprise Grade  
+**GitHub PR**: #93 (6 commits, comprehensive code review)
+
+## Problem Statement
+n8n workflows were stored only in PostgreSQL database without version control, creating risks of data loss and making it difficult to track changes, deploy to different environments, and collaborate on workflow development.
+
+## Solution Implemented
+Created a minimal, enterprise-grade automated backup system that exports n8n workflows to a Git repository with the following features:
+
+### Core Components
+1. **Workflow Export Script** (`scripts/n8n-backup.sh`)
+   - POSIX-compatible automation with strict mode
+   - Automated n8n CLI workflow export
+   - Modern Git practices (main branch, local config)
+   - Comprehensive staging and push logic
+   - Dynamic branch detection and upstream tracking
+
+2. **Docker Integration**
+   - Secure package installation with version pinning
+   - Volume mapping for script access
+   - Persistent storage in n8n_data volume
+   - Hadolint-compliant Dockerfile
+
+3. **Code Review Integration**
+   - CodeRabbit AI filtering configuration
+   - GitHub Actions compatibility
+   - Security best practices compliance
+
+4. **Directory Structure**
+   ```
+   /home/node/.n8n/workflows/
+   ├── .git/              # Git repository
+   ├── README.md          # Documentation
+   └── (exported workflows in JSON format)
+   ```
+

+## Code Review Process & Improvements
+
+### GitHub PR #93 Evolution
+**Initial Implementation → Enterprise-Grade Solution through peer review**
+
+#### CodeRabbit AI Feedback Integration
+1. **POSIX Compatibility Enhancement**
+   ```bash
+   # Before: Non-portable strict mode
+   set -euo pipefail
+
+   # After: POSIX-compatible conditional pipefail
+   set -eu
+   if (set -o 2>/dev/null | grep -q pipefail); then
+     set -o pipefail
+   fi
+   ```
+
+2. **Enhanced Error Handling**
+   ```bash
+   # Before: Basic directory change
+   cd /home/node/.n8n/workflows
+
+   # After: Validated directory change
+   cd /home/node/.n8n/workflows || exit 1
+   ```
+
+3. **Modern Git Practices**
+   ```bash
+   # Before: Default branch behavior
+   git init
+   git config user.name "n8n-bot"
+   git add .
+
+   # After: Explicit modern practices
+   git init -b main
+   git config --local user.name "n8n-bot"
+   git add -A
+   ```
+
+4. **Improved Push Logic**
+   ```bash
+   # Before: Push only on new commits
+   if new_commits; then push; fi
+
+   # After: Always push when remote configured
+   # Handles unpushed commits from previous runs
+   CURRENT_BRANCH="$(git rev-parse --abbrev-ref HEAD)"
+   git push -u origin "$CURRENT_BRANCH"
+   ```
+
+5. **Docker Security Compliance**
+   ```dockerfile
+   # Before: Unversioned package
+   RUN apk add --no-cache git
+
+   # After: Pinned version for security
+   RUN apk add --no-cache git=2.47.3-r0
+   ```
