Informations about the package backup4wp

Backup4WP

You know the problem, you've created a backup for your website using a WordPress backup plugin and your WordPress website breaks after an update. Next you can't restore your website to the previous version because you can't access the WP dashboard anymore. Using this backup tool you're able to create a backup outside WordPress. Access the tool again if you need to restore the website. We use the tool to create backups if we install a new theme / plugin or before we do some (smaller) updates.

[!TIP] Now it is also possible to install Backup4WP via the WordPress dashboard. Download the plugin from our website and install the recent version of Backup4WP with a simple mouse click.

How does it work?

The backup tool makes a copy from your WordPress website and saves the files in a directory outside the public directory. A database dump is saved in the same directory. During the restore function the files from the backup are moved back to the original location. The database dump is used to restore the database as well.

Test the tool first!

This tool is using the Linux command line tool "rsync" to copy all the files. We're using the tool for years and it works perfect on all our web servers. It might break your website during a restore action, so try the backup tool first on a similar test/staging site.

Security

The tool doesn't store any database logins and all files are saved in a directory which is not accessible via the public website. To access the Backup4WP tool, you need to authorize via a link that is send to your own email address. The session expires 4 hours of activity.

If your web host is based on Apache, there is an option to protect the directory using a login/password or by white-listing your IP address.

Features

Installation

Using Composer, just run the following code within the public HTML directory from your WordPress website:

Replace the directory name "mybackup" with your unique name, if you like.

Manual installation

Download the the zip file here. Extract and upload the files into a directory named "mybackup" (or some other name) right into the website's public folder. Access the tool, enter your email address and enter your MailerSend API key or your SMTP credentials. Confirm your email address via the link you get in your mailbox.

If you like to use the authorization feature provided by Apache, than continue to "Apache authentication" and enter your details on that page. If you need the "Download" option for your backups, you need to change the variable ENABLE_DOWNLOADS to "true" inside the file libs > func.php.

Installation snippet for ManageWP users

Use this snippet if you use ManageWP. Just run the code and access the tool and finish the "Installation". Continue with the Installation as subscribed before!

<?php
$dir = dirname(dirname(dirname(__DIR__))).'/mybackup';
if (file_exists($dir)) {
    echo 'A "mybackup" directory already exists!';
} else {
    exec('composer -V', $output);
    if (substr($output[0], 0, 8) == 'Composer') {
        exec('composer create-project finalwebsites/backup4wp:dev-master mybackup'); // you can use a different directory name (instead of "mybackup")
        echo 'Downloaded and installed Backup4WP using Composer';
    } else {
        echo 'Composer isn\'t supported by your web host.';
    }
}

Update notes

17th November 2024 Added a simple update function. If you install Backup4WP via Composer, you can update the backup tool via the update page (link in the menu). The log-out link is fixed and redirets to the login page now.

5th January 2024 Inside the function get_db_conn_vals() there was a check for the existens of enviroment variabels. This old check worked only with some "rare" configurations. The check is replaced and the phpdotenv class is used to read the .env file from a website.

18th March 2023 In this version we replaced the Sendgrid email option with MailerSend. Sendgrid changed their offer and the free option with 12.000 monthly emails isn't available anymore (for new accounts). In place of the Sendgrid API, you can use the Mailersend API. Their free version has also 3.000 emails per month, but they offer also other options, Sendgrid doesn't offer. If you still prefer Sendgrid, you can still use Backup4WP while using the SMTP email option.

4th November 2022 In some situations there was a PHP memory error while reading the database backup in the restore mode. We fixed it by reading the file line by line using fgets() instead of the file() function.

11th September 2022 We did several updates and bug fixes for the login function and the options page. In the past it doesn't worked well during the setup, if some setting wasn't correct. These should be fixed now. There is also also a log out function available now. We advise to update the application immediately to prevent yourself from future problems. You can keep you current database and files, only the files from the application are modified.

1st May 2022 First release v1.1.0, from today on we're using release tags. Do you like to use Composer? Than is this update for you. We packaged Backup4WP and you're able to install the tool using Composer. The PHPMailer, Sendgrid and Mysqldump library are not included in our distribution anymore. Don't worry for the manual installation, we offer a ZIP file with all the library files included. During the installation, you can choose the directory name. Instead of "mybackup", you can use your own name. This makes it a bit more safe if you choose a random name. From our prospective it's safe to update the application for installations from the last year.

17th April 2022 If your WordPress website is using the Easy SMTP plugin, Backup4WP will recognize these settings too. Plus, if you use an API key from Sendgrid as a password for this SMTP plugin, the API key is also pre-filled inside the "Sendgrid" section. We changed also the order on how the obtained settings are used: 1. Easy SMTP, 2. WP Mail SMTP and 3. the old Sendgrid plugin.

3rd April 2022 If you like to download your backups, it's necessary now to set the constant variable to "true" inside the file "func.php". Most people doesn't need the download feature. This modification is temporary solution until we find a better way to do this on the options page.

19th March 2022 The email sender name is now the domain name. That makes it easier to recognize the email message in your inbox if you use the Backup4WP tool for multiple websites.

30th January 2021 The directory structure for single backup is changed. The site files are stored in a separate directory now. Remove old backups before you update to the latest version of Backup4WP. The restore function will not work with old backups. Beside the new directory structure, we added a new feature: Downloads. Now you can download your entire backup as one ZIP file. The structure of the ZIP file is compatible with the site import function in Local (by Flywheel).

12th December 2020 Some users doesn't like the authorization via the magic link. That's the reason that we've placed the "old" Apache authorization method back to the backup tool. If you enable the Apache authorization option, the email based method isn't used anymore.

14th September 2020 We changed the options page that users can use their SMTP server credentials now. To keep those settings in Backup4WP, we added several columns to the table "backupsettings". To get the update you need to replace the whole "mybackup" directory (keep your "backups" directory!) and visit the main page. The function "update_mybackup()" will add the missing database table columns. Optionally, add your own SMTP server credentials.
