📊 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:

# 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.
