The Ultimate Guide: How to Backup Your Website Before Changing Hosts

Changing your web host is a lot like moving to a new house. It’s an exciting step towards a better environment—perhaps faster loading speeds, improved security, or more responsive customer support. But before you pack a single box, you face the daunting task of inventorying all your belongings and ensuring nothing gets lost or broken in transit.

In the digital world, your website’s files, databases, emails, and configurations are your most valuable possessions. A single misstep during a host migration can lead to broken links, lost data, extended downtime, and a catastrophic hit to your search engine rankings and user trust.

This is why creating a complete, verified backup of your entire website is the non-negotiable first step. It is your insurance policy. If anything goes wrong during the migration process, you have a perfect snapshot to restore, allowing you to try again without starting from scratch.

This definitive guide is designed to be your trusted moving consultant. We will walk you through, in meticulous detail, exactly how to backup your website before changing hosts. We’ll cover everything from the fundamental concepts to the practical, step-by-step processes for both manual backups and automated plugin methods. By the end of this guide, you will possess the knowledge and confidence to execute this critical task flawlessly.

Part 1: Understanding the “What” and “Why” – The Foundation of a Safe Migration

Before we dive into the “how,” it’s crucial to understand what you’re actually backing up and why this process is so vital.

What Exactly Are You Backing Up?

A website is not a single file; it’s a complex ecosystem of interconnected components. A true full backup encompasses two primary elements:

1. Website Files: These are all the raw materials that make up your site’s structure and appearance. They are typically stored in a directory on your server, often called public_html, www, or your domain name.
   • Core CMS Files: The essential code for systems like WordPress, Joomla, or Drupal.
   • Themes & Templates: The files that control your site’s design and layout.
   • Plugins, Modules, & Extensions: The add-ons that provide extra functionality (contact forms, SEO tools, etc.).
   • Media Library: Every image, PDF, video, and document you’ve ever uploaded.
   • JavaScript, CSS, & Other Assets: The code that controls interactivity and styling.
2. Website Database: This is the dynamic brain of your operation. If your site uses a Content Management System (CMS) or has any interactive elements (like user logins, comments, or e-commerce), it relies on a database. The database stores:
   • All your pages, posts, and custom post types.
   • Every comment from your users.
   • User information and login credentials.
   • Website settings, plugin configurations, and theme options.
   • E-commerce data like products, orders, and customer details.

Backing up only your files but not your database would leave you with a beautiful, empty shell of a website. Backing up only the database would give you all your content with no design or structure to display it. You need both.

The Non-Negotiable “Why”: The Consequences of Skipping a Backup

“Why can’t I just copy the files directly to the new host?” This is a common question. The migration process itself involves moving data, but having a separate, local backup is your safety net. Here’s what could go wrong without one:

• Data Corruption During Transfer: File transfers over the internet are not infallible. A connection drop could corrupt a critical file or database table.
• Accidental Deletion: It’s surprisingly easy to accidentally overwrite or delete the wrong file on the new server during setup.
• Incompatibility Issues: The new server might have a different version of PHP or other software, causing your site to break. Without a backup, rolling back to the old host becomes a nightmare.
• Security Breaches: The brief window during a migration can sometimes be exploited if security isn’t tight. A backup allows you to restore a clean version.
• Peace of Mind: Knowing you have a perfect copy of your site stored safely on your own computer eliminates the fear and stress of the migration process. It empowers you to proceed with confidence.

Part 2: Pre-Backup Preparation: Laying the Groundwork

A little preparation now will save you a massive headache later. Before you create a single download link, complete these essential steps.

Step 1: Audit Your Current Website

Spend 30 minutes thoroughly browsing your own site. Click on every page, test your contact forms, and ensure all your plugins are functioning. Make a note of any issues. This gives you a “before” benchmark, so you can verify everything works correctly on the new host after the move.

Step 2: Gather Your Credentials

You will need access to several key areas. Have these login details ready:

• Your Current Web Hosting Control Panel (e.g., cPanel, Plesk, DirectAdmin): This is where you’ll access file managers and database tools.
• Your WordPress Admin Dashboard (if applicable): For using backup plugins.
• Your Domain Registrar: You won’t need this for the backup, but you will for the final step of pointing your domain to the new host.

Step 3: Choose Your Backup Method

There are two main paths you can take, and your choice will depend on your technical comfort level and the size of your website.

• Method A: Manual Backup via cPanel (The “Do-It-Yourself” Approach): This method gives you the most control. You will directly download your files and export your database. It’s highly reliable and doesn’t rely on any third-party plugins. We recommend this for users who are comfortable with basic technical tasks.
• Method B: Backup via a WordPress Plugin (The “Automated” Approach): If your site is built on WordPress, plugins like UpdraftPlus or Duplicator can simplify the process into a few clicks. They bundle your files and database into a single package. This is excellent for less technical users or for very large sites where manual downloading could be cumbersome.

For the purposes of this guide, we will provide a deep dive into both methods.

Part 3: Method A – The Comprehensive Manual Backup via cPanel

The vast majority of shared hosting providers use cPanel as their management interface. This section will guide you through the manual process.

A1: Backing Up Your Website Files Using File Manager

1. Log in to your cPanel. The URL is typically http://yourdomain.com/cpanel or a specific URL provided by your host. Enter your username and password.
2. Locate and open the “File Manager” icon.
3. Navigate to Your Root Directory. In the left-hand sidebar, you need to select the main folder that contains your website. This is usually public_html, www, or a folder named after your domain. If you have addon domains or subdomains, they will have their own separate folders.
4. Select All Files and Folders. Once inside your root website directory, click on any file, then press Ctrl+A (or Cmd+A on Mac) to select everything. Be sure you are selecting all the contents inside public_html, not the public_html folder itself.
5. Compress the Files. Right-click on the selected items and choose “Compress” from the context menu.
6. Choose Compression Type. A dialog box will appear. Select ZIP Archive as the compression type. It is widely supported and easy to work with on most operating systems. You can name the archive something descriptive like full-website-backup-[date].zip.
7. Start the Compression. Click the “Compress File(s)” button. The time this takes depends on the size of your website. For large sites, this could take several minutes.
8. Download the Archive. Once the process is complete, you will see the new ZIP file in your File Manager. Right-click on it and select “Download.” Ensure the download completes fully before proceeding. This file is now a backup of all your website’s core files, themes, plugins, and uploads.

A2: Backing Up Your Website Database Using phpMyAdmin

Now, we turn our attention to the database.

1. Back in cPanel, find and click on “phpMyAdmin.” This is the standard tool for managing MySQL databases.
2. Select Your Database. On the left-hand panel, you will see a list of databases. Click on the one that corresponds to your website. If you’re unsure which one it is, you can find the database name in your website’s configuration file. For WordPress, this is the wp-config.php file in your root directory; look for the line that says define('DB_NAME', ...).
3. Export the Database. With your database selected, click the “Export” tab in the top menu.
4. Choose Export Method. For a standard backup, the “Quick” method and “SQL” format are perfectly adequate. However, for maximum control and compatibility, we recommend the “Custom” method.
5. Configure Custom Export (Recommended):
   • Output: Ensure it’s set to save as a file.
   • Format: Stick with SQL.
   • Tables: Leave all tables selected.
   • Output: Check the box for “Add DROP TABLE / VIEW / PROCEDURE”. This option helps avoid errors during a restore by first removing any existing tables with the same name.
   • Check the box for “Add IF NOT EXISTS” for extra safety.
   • Under “Object creation options,” check “Add CREATE PROCEDURE / FUNCTION / EVENT”.
6. Execute the Export. Click the “Go” button. Your browser will download an .sql file. This file contains all the instructions to recreate your entire database, with all its content and structure, from scratch.

A3: Don’t Forget Your Email Accounts (If Applicable)

If you use your hosting for email (e.g., you@yourdomain.com), you need to back this up separately. In cPanel, look for the “Email” section. You can often use tools like “Email Forwarders” to forward important emails to a Gmail account temporarily, or use “IMAP” in an email client like Thunderbird or Outlook to download all your emails locally to your computer.

Part 4: Method B – The Streamlined WordPress Plugin Backup

For WordPress users, plugins can automate the bundling of both files and databases. We’ll use the popular (and free) UpdraftPlus plugin for this example.

B1: Installing and Configuring UpdraftPlus

1. Log in to your WordPress Admin Dashboard.
2. Navigate to Plugins > Add New.
3. Search for “UpdraftPlus“ and click “Install Now,” then “Activate.”
4. Go to Settings > UpdraftPlus Backups.
5. Create a Manual Backup: In the main tab, click the giant “Backup Now” button.
6. Choose What to Backup. A pop-up will appear. It’s wise to leave both boxes checked: “Include your database in the backup” and “Include your files in the backup.” Click “Backup Now.”

UpdraftPlus will now begin the process. You can see the progress on the page. It will create separate archives for your plugins, themes, uploads, and other files, plus one for your database.

B2: Downloading the Backup Files to Your Computer

Once the backup is complete, you must download the files to your local machine. Storing them only on your server defeats the purpose of a safety net.

1. In UpdraftPlus, go to the “Existing Backups” tab.
2. You will see a list of your recent backups. For each set, you will see several archive files (e.g., plugins.zip, themes.zip, uploads.zip, db.sql.gz).
3. Click the “Download” button for each and every one of these files. Save them all into a single, well-labeled folder on your computer (e.g., Website-Backup-[Date]).

Pro Tip: Both UpdraftPlus and competitors like Duplicator or All-in-One WP Migration can also create a single, restorable “migration” package. Duplicator, in particular, is excellent for actually performing the host migration itself, as it creates an installer script.

Part 5: The Crucial Verification Step – Don’t Skip This!

You have a bunch of downloaded files on your computer. But are they good? The only way to know for sure is to verify their integrity. The most robust way to do this is to perform a test restore on a local environment.

This involves setting up a local server on your computer using software like LocalWP (for WordPress), XAMPP, or MAMP. You can then:

1. Create a new, empty database in your local server software.
2. Import your downloaded .sql file into this new database using phpMyAdmin.
3. Extract your downloaded website files (the ZIP archive) into the local server’s htdocs or equivalent folder.
4. Update the local configuration file (e.g., wp-config.php for WordPress) to connect to the new local database.
5. Access your site via http://localhost.

If your site loads perfectly locally, with all content, images, and functionality intact, congratulations! Your backup is verified and 100% sound. If it doesn’t, you have identified a problem before you’ve canceled your old hosting, and you can re-create the backup.

Part 6: Secure Storage and Final Checklist

A backup is only useful if it’s safe and accessible.

• The 3-2-1 Backup Rule: For critical data, follow this best practice: Have at least 3 total copies of your data, store them on 2 different types of media (e.g., your computer’s hard drive and a cloud service like Google Drive or Dropbox), with at least 1 copy stored off-site (the cloud service fulfills this).
• Encrypt Sensitive Backups: If your site handles sensitive user data, consider encrypting your backup files before uploading them to the cloud.
• Final Pre-Migration Checklist:
  • Full Website File Backup (.zip file) is downloaded.
  • Complete Database Backup (.sql file) is downloaded.
  • Email data is backed up (if applicable).
  • Backup has been verified via a test restore (highly recommended).
  • Backups are stored in at least two separate, secure locations.
  • You have all necessary login details for your NEW web host.
