+# .env Backup Integration Guide
+
+## Quick Setup Summary
+
+Your .env backup system is now fully operational! Here's what was set up:
+
+### ✅ What's Working
+
+- **31 .env files** discovered across your Docker containers
+- **30 files backed up** successfully to `/home/acedanger/.env-backup`
+- **Private Gitea repository** configured and pushed successfully
+- **Version control** with automatic commit messages and timestamps
+- **Reference files** included (docker-compose.yml for context)
+
+### 🔧 Integration Options
+
+#### 1. Manual Backup (Current)
+
+```bash
+cd /home/acedanger/shell
+./backup-env-files.sh              # Regular backup
+./backup-env-files.sh --dry-run     # Preview changes
+./backup-env-files.sh --list        # Show all .env files
+```
+
+#### 2. Automated Daily Backup (Recommended)
+
+Add to your crontab for daily backups at 2 AM:
+
+```bash
+# Daily .env backup at 2 AM
+0 2 * * * /home/acedanger/shell/backup-env-files.sh >/dev/null 2>&1
+```
+
+#### 3. Integration with Existing Backup Scripts
+
+The backup integrates with your existing backup system through:
+
+- **Logs**: Written to `/home/acedanger/shell/logs/env-backup.log`
+- **Completion**: Tab completion available via `env-backup-completion.bash`
+- **Validation**: Use `validate-env-backups.sh` for integrity checks
+
+### 🔐 Security Features
+
+1. **Private Repository**: Only you have access
+2. **Gitignore**: Excludes temporary files and logs
+3. **SSH Authentication**: Uses your existing SSH key
+4. **Local + Remote**: Dual backup (local git + remote Gitea)
+
+### 📊 Backup Structure

+```
+
+### 🔄 Common Operations
+
+#### Restore Files (if needed)
+
+```bash
+./backup-env-files.sh --restore
+```
+
+#### Force Backup (ignore unchanged files)
+
+```bash
+./backup-env-files.sh --force
+```
+
+#### Check What Would Change
+
+```bash
+./backup-env-files.sh --dry-run
+```
+
+### 🚨 Emergency Recovery
+
+If you lose your filesystem:
+
+1. **Clone the backup**: `git clone https://git.ptrwd.com/peterwood/docker-env-backup.git`
+2. **Restore files**: `./backup-env-files.sh --restore`
+3. **Recreate containers**: Your docker-compose.yml reference files are included
+
+### 📈 Monitoring
+
+- **Logs**: Check `/home/acedanger/shell/logs/env-backup.log`
+- **Git History**: View changes with `git log` in backup directory
+- **Validation**: Run `validate-env-backups.sh` for integrity checks
+
+### 🔧 Maintenance
+
+#### Weekly Validation (Recommended)
+
+```bash
+# Add to crontab for weekly validation
+0 3 * * 0 /home/acedanger/shell/validate-env-backups.sh >/dev/null 2>&1
+```
+
+#### Cleanup Old Logs (Monthly)
+
+The system automatically manages logs, but you can clean them manually if needed.
+
+### 🆘 Troubleshooting
+
+#### Push Fails
+
+- Check SSH key: `ssh -T git@git.ptrwd.com`
+- Verify repository exists and is private
+- Check network connectivity
+
+#### Files Not Found
+
+- Verify Docker directory structure: `ls -la ~/docker/*/`
+- Check file permissions
+- Run with `--list` to see what's detected
+
+#### Restore Issues
+
+- Ensure target directories exist
+- Check file permissions
+- Use `--dry-run` first to preview
+
+## Integration Complete! 🎉
+
+Your .env files are now safely backed up and version controlled. The system will:
+
+1. Track all changes to your .env files
+2. Maintain a secure backup in your private Gitea
+3. Provide easy restore capabilities
+4. Integrate with your existing shell toolkit
+
+Run `./backup-env-files.sh` regularly or set up the cron job for automatic backups!
