Download the PHP package mikailfaruqali/backup without Composer

Laravel Backup Package

Generate on-demand MySQL database backups and download them as password-protected, AES‑256 encrypted ZIP files via a simple HTTP route.

Built for simplicity, performance, and easy integration into existing Laravel apps.

Features

• One-click/download database backup via HTTP route
• ZIP encryption using AES‑256 (ZipArchive::EM_AES_256)
• Password protection for the ZIP file
• Configurable route prefix and middleware
• Customizable download filename
• Support for custom mysqldump binary path (Windows/Linux/macOS)
• Streams response and cleans up temporary files automatically

Requirements

• PHP >= 7.4
• Laravel framework (or illuminate/contracts) >= 5.0
• PHP ZipArchive extension enabled
• MySQL database connection configured in config/database.php
• spatie/db-dumper (installed as a dependency)

Installation

Install via Composer:

Laravel will auto-discover the service provider.

Configuration

Publish the configuration file to your app (it will create config/snawbar-backup.php):

Available options (defaults shown):

Notes:

• The package code will also accept callables for file_name and zip_password. However, Laravel's config cache cannot serialize closures. Prefer static strings in your config file. If you need dynamic values, set them at runtime (e.g., in middleware) using config([...]) before the request hits the controller, and avoid caching config or provide a non-closure value when cached.

Routes and Usage

This package registers the following route by default:

• GET /{prefix}/download → streams a password-protected ZIP containing a MySQL dump

Where {prefix} is the value of snawbar-backup.route (default: backup).

Examples:

• Default URL: /backup/download
• Custom prefix admin/backup: /admin/backup/download

The route name is snawbar.backup.download.

Downloading a backup

• Visit the route in your browser, e.g. https://your-app.test/backup/download
• Or using curl:

The response is a streamed download of an encrypted ZIP whose filename is taken from snawbar-backup.file_name. Use the password from snawbar-backup.zip_password to open the archive.

Security and Access Control

The download route is as secure as the middleware you attach to it. By default it uses the web middleware group only. You should restrict access in production.

Recommended options:

• Require authentication: set 'middleware' => ['web', 'auth']
• Restrict to authorized roles/abilities: 'middleware' => ['web', 'auth', 'can:download-backup']
• Use IP allow-lists or custom middleware for extra checks
• Consider signed routes or additional secrets when exposing via the internet

Update config/snawbar-backup.php accordingly and clear caches:

Database Connection

Backups use your default mysql connection from config/database.php:

• Host: database.connections.mysql.host
• Database: database.connections.mysql.database
• Username: database.connections.mysql.username
• Password: database.connections.mysql.password

Ensure these are set (typically via your .env).

mysqldump Path (especially on Windows)

If mysqldump isn't available in the system PATH, set mysql_dump_path in config/snawbar-backup.php:

• Windows (XAMPP example): C:/xampp/mysql/bin/mysqldump.exe
• WSL/Linux: /usr/bin/mysqldump
• macOS (Homebrew): /opt/homebrew/bin/mysqldump or /usr/local/bin/mysqldump

How it Works

Under the hood (simplified):

1. Create a temporary .sql dump using spatie/db-dumper and mysqldump.
2. Create a temporary .zip with ZipArchive, set password and AES‑256 encryption, add the SQL file.
3. Stream the ZIP to the client as the response filename from file_name.
4. Delete the temporary files after streaming.

Troubleshooting

• ZIP won't open / wrong password

  • Verify zip_password in config/snawbar-backup.php
  • Ensure no whitespace or unexpected characters

• 500 error: Failed to create ZIP archive

  • Confirm PHP ZipArchive extension is installed and enabled
  • Ensure the PHP process can write to the temp directory (sys_get_temp_dir())

• mysqldump not found or permission denied

  • Set mysql_dump_path to the absolute path of mysqldump
  • Ensure the PHP user can execute mysqldump

• Empty or partial dump

  • Check DB credentials in config/database.php
  • Large databases may require increasing PHP max_execution_time and memory limits
• Route not found
  • Clear caches: php artisan route:clear; php artisan config:clear
  • Confirm your app is loading package routes and provider (auto-discovery)

Limitations and Notes

• Currently supports the default mysql connection. For other drivers, extend the controller as needed.
• Configuration closures are not compatible with php artisan config:cache.
• The backup is generated on-demand per request; there's no scheduled/queued command included by default.
