Self-hosting WordPress offers complete freedom, but imposes a major responsibility: managing your own data. Whether you are on a VPS, dedicated server, or cloud infrastructure, knowing how to restore your site is a digital survival skill.

1. Why Backup Is Your Only True Lifeline

Before addressing the technical aspects, let us recall why a backup strategy is not optional. It is your safety net against four major threats:

• The risk of hacking: WordPress is a frequent target. A clean backup is often the fastest way to clean an infected site.
• Update errors: An incompatible plugin or theme can break your layout or make the administration inaccessible.
• Human error: Accidental deletion of a directory or incorrect database manipulation happens even to the best.
• Hardware failure: Even with major hosting providers, a disk can fail. Without an externalized copy, it is total loss.
• Major disaster: fire, water damage

2. Anatomy of a WordPress Site

To understand restoration, you must visualize what we are backing up. WordPress is not a single block, but the fusion of two entities that must be perfectly synchronized:

1. The File System: It contains the WordPress core, your themes, your plugins, and especially your media (images, documents).
2. The Database: It contains the “brain” of the site: article text, settings, user accounts, and links.
3. Apache (Web Server): It acts as an intermediary between visitors and WordPress. Apache receives HTTP requests from browsers (when someone visits the site), executes WordPress via PHP, then returns the generated pages (HTML, images, scripts) to users. It is what makes the site accessible on the Internet. Other solutions exist but they will not be covered in this article

Golden rule: Restoring files without the corresponding database (or vice versa) from the same point in time will result in desynchronization and a dysfunctional site. WordPress relies on a LAMP (Linux – Apache – MySQL – PHP) architecture, a principle that applies more broadly to all similar web architectures based on the separation between server, application, and database.

3. The Technical Restoration Procedure with Bareos

Step 1: Restoration of System Directories

We instruct Bareos to restore the three critical server locations:

• The site folder (/var/www/) containing the WordPress code and media.
• The web server configuration files (/etc/apache2 or /etc/httpd) to preserve VirtualHosts and redirection rules.
• The SSL certificate folder (/etc/letsencrypt/) to maintain HTTPS.

Step 2: Reinstallation of the Technical Stack (LAMP)

On the destination server, we install the packages required to run the site: the web server (Apache), the database engine (MariaDB/MySQL), Certbot, and the precise version of PHP (with its modules) used during the backup. We then enable the corresponding services.

Step 3: Database Reconstruction

Rather than overwriting, we perform a clean reconstruction: creating a blank database and a user with associated privileges. The SQL backup file (“dump”) is then decompressed and injected directly into this new database.

Step 4: Restart and Validation

We restart the web service to load the restored configurations. Finally, we execute an SSL certificate verification command (dry-run) to validate that encryption is active and functional before opening traffic.

Conclusion: Mastery Lies in Anticipation

Consumer-grade tools exist for making simple copies. But as soon as you deal with critical environments, mastery of the operating system and tools like Bareos becomes essential.

At Data-perspective, we do not simply store your data. We guarantee complete mastery of the reconstruction process. In the event of an incident, we do not just “return files”: we rebuild your complete digital environment for fast and reliable restoration.
