6. **File Upload Support**: Interface ready for testing restore functionality
7. **S3/MinIO Preparation**: Infrastructure prepared for cloud storage integration

### 📊 Test Results

#### Backup Creation Test
- **Test Date**: September 17, 2025 10:08 AM
- **Backup Name**: "TigerStyle Life9 - Backup Plugin Testing-2025-09-17-10-08"
- **File Size**: 27.45 MB
- **Contents**: 
  - ✅ WordPress Files & Uploads
  - ✅ Complete Database Export (920 KB SQL file)
- **Storage Location**: Local filesystem
- **Creation Time**: ~30 seconds
- **Result**: ✅ **SUCCESS**

#### Infrastructure Validation
- ✅ **Apache Configuration**: Running as user 1000:1000 (resolved permission conflicts)
- ✅ **PHP Configuration**: 512M memory limit, 300s execution time for large backups
- ✅ **File Permissions**: Backup directory properly owned by container user
- ✅ **ZIP Creation**: PclZip working reliably vs problematic ZipArchive
- ✅ **Database Export**: MySQL dump functionality operational
- ✅ **WordPress Integration**: Plugin system, admin menus, and hooks functioning

## 🔧 Technical Implementation Details

### Key Problem Solved: Permission Issues
**Root Cause**: ZipArchive was failing due to Apache running as www-data while container user was 1000:1000

**Solution Applied**:
```yaml
# Docker Compose Configuration
environment:
  APACHE_RUN_USER: "#1000"
  APACHE_RUN_GROUP: "#1000"
```

**Result**: Apache now runs PHP processes as user 1000, matching container user and file ownership.
