As much as I love the WordPress software, sometimes things happen. Your site may crash, a login might be hacked, you may need to move your site to another host, or you may want to move your site to another CMS altogether.
Moving website files is scary. I’m not going to pretend that it ever isn’t. Even when I feel confident that I know what I’m doing, it feels like something can still go wrong. So don’t feel alone if you feel the same way!
That doesn’t mean that you can’t have a strong knowledge of HOW to do it. If you do or plan to manage a WordPress site, you should know how to take backups, restore from a backup, and how to migrate a website. You never know when something may happen that will require a backup, or when you may need to move your site somewhere else.
Backup and Migration Basics
First, we need to understand how WordPress is structured.
A WordPress site is essentially made up of two parts: the files and the database.
The files are what you get when you click download on WordPress.org: a zip folder that contains many folders, each of which contain files. The files can include:
- Pictures and media
- WordPress dashboard files
- Theme files
- Plugin files
The database is created on your server. It’s a storage for all your website data using something called MySQL. The database can include:
- Page text
- Post text
- WordPress settings
- Theme settings
- Plugin settings
When backing up or moving a site, both of these things need to be moved and both need to be connected to each other. There’s a file called wp-config that contains PHP which connects the files to the database using a database name, user, and password. It’s very possible that if you are moving a site and get a database error, it’s because something went wrong with these credentials.
Now that’s a very quick and basic run-down. If you want to learn more about files and databases, I highly recommend this article from MalCare. You don’t need to understand all these things in order to run backups or migrate, but they are extremely useful to know in case something goes wrong.
Taking Backups
A backup is a copy of your site taken at any given point that can theoretically be used to replace a future version of your site. They are extremely useful to have. I’ve always recommended at least taking monthly backups. If you have a ton of traffic, post a lot of new content, or sell a lot through the site, more frequent backups are better. Some sites with huge numbers of sales per day take a backup once a minute!
There are two ways to take backups – manually, or through a third-party tool like a plugin.
Manual Backups
You can manually take backups using cPanel, however this method is becoming outdated.
You can also take manual backups using FTP. Open up your FTP client and find the root directory of your website. The root directory contains folders like wp-content and wp-admin, so if you see those, you are in the right place. Choose which folder to backup, or choose multiple. You can select and right-click on them, then choose download. Save the files on your computer or on a cloud drive.
But wait – we only saved the files. What about the database?
Depending on the web host you’re using, these steps may change a little. But here’s the gist. In your hosting account, go to the cPanel or wherever your dev tools are. Find a menu item called phpMyAdmin and select it. You’ll see the database(s) on the left. Select the one that you want to backup. Then choose all the tables you want to backup. Choose Export from the top menu. Then choose Go. This will save the SQL file on your computer, or you can move it to a cloud drive.

Assisted Backups
The above methods involve going into your files directly. Perhaps you don’t want to do that, can’t access those files (Managed WordPress hosting can make that hard) or you want to automate the backups so you don’t have to do them yourself.
There are tons of plugins and tools that specialize in taking backups. My favorite is what we use at Web Pro Geeks to manage our client sites: ManageWP. Within it, you can schedule backups at whatever interval you want. The program downloads the backups automatically. You can then go into the site within ManageWP and select to view or restore from a backup. ManageWP does it all for you.
Plugins are also a good way to take backups. However keep in mind that if a site crashes and you need to restore it, chances are the plugin won’t be accessible. This is why it’s so important to store backups in multiple places.
You can use plugins like Updraft Plus or Duplicator to schedule backups. They give you the option to store backups in the cloud. That way, if the plugin settings are unavailable, you can still access the copies of the website. Each plugin has different setup instructions, so choose the one that looks best and get to work!
Restoring from a Backup
Taking the backups themselves is great. And totally necessary. But the backups are only valuable if you can actually use them in an emergency. Restoring a site from a backup can be tricky, so take a deep breath and take your time.
If you use the plugin method: The first step is to delete all the WordPress files currently active. Do that using FTP – select and delete all the files and folders within the root. If you have a local backup of your files, upload them here. Or, you can download WordPress fresh from WordPress.org and install those files. Now, you should be able to log in to WordPress and restore your backups using your plugin.
To restore a database, log in to your host and access phpMyAdmin like we did before. Last time, we performed an export. Now, we need to perform an import. Select your chosen database, then choose Import from the top menu. Select Choose File under File to Import, then select your backed up database. Make sure the format is SQL then click Go.
Migrating a Site
Guess what? Since you now know how to restore a backup, you know almost everything there is to know about migrating a site! You’ll follow the steps we just outlined on the new server instead of on your existing one!
(Keep in mind that some hosts offer migration services – check in with yours to see.)
There are a few things you’ll want to make sure you do when migrating a site using a backup.
- Edit your wp-config.php file. Open this one up using FTP and find the DB_name, DB_user, and DB_password. These will most likely point toward your old database. Make sure that these match the values of whatever current database you’re using.
- Configure and Change the DNS. The Domain Name Server has to be pointed toward the correct host. Otherwise, your domain name will try to send visitors to the old host where your files don’t exist. On your new hosting account find the DNS details section in your settings. Find the CNAME record and A NAME for your website. Contact wherever you purchased your domain from, and request these values to enter into these sections. You may actually be able to just look it up without contacting anyone.
Believe it or not, that’s pretty much all you need to know in order to begin your migration.
