There are always good reasons for having a backup of a WordPress website. If only so that no data is lost or that all data can be restored immediately in the event of a hacker attack. In this article, we’ll show why it’s best to start backing up right away!
La perte de données peut toucher n'importe qui
Even if one thinks that everything that has been worked out is well-stored on the WordPress website, it can still happen that important data is accidentally deleted. Be it because it was hectic and you forgot to save your final data, or because a colleague was working on the same website, thought a document stored there was out of date and simply deleted it. The possibilities are innumerable and can occur unexpectedly.
C'est pourquoi il est d'autant plus important de sauvegarder toutes les données. Mais même sans intervention humaine, des pertes de données systémiques se produisent régulièrement. Assurez-vous donc de disposer d'une sauvegarde à partir de laquelle vous pourrez facilement restaurer vos données dans le système en cas d'urgence. Pour ce faire, il est possible, voire recommandé, d'effectuer plusieurs sauvegardes et de les stocker à différents emplacements, par exemple une copie sur le serveur et une autre dans le cloud. Ainsi, vous aurez vos données à portée de main en cas de perte.
1. Erreur humaine – Lorsque les humains traitent des données…
Comme nous l'avons brièvement évoqué dans la section précédente, les humains peuvent eux aussi être à l'origine de pertes de données. Personne n'est à l'abri d'une erreur. Bien sûr, vous pouvez toujours essayer de récupérer vous-même les données perdues.
Ultimately, one will not be able to avoid a professional data backup to restore the WordPress website here either. And in the best case, several times a day or week, so that all processing phases are documented and data can be restored more quickly.
2. Mises à jour – L'inconnu
Doesn’t that sound familiar? You want to “just quickly” perform a “simple” WordPress update because you have just received a friendly message saying that it is important. And of course it is important so that your WordPress website can continue to function smoothly.
Mais il arrive parfois que la mise à jour tourne mal et que le site web ne s'affiche plus comme avant. Dans ce cas, vous pouvez vous estimer heureux si vous avez effectué une sauvegarde de la base de données en temps voulu – qu'elle soit automatique ou manuelle –, car il vous suffira alors de restaurer vos données.
3. La mise à jour est une chose, l'installation en est une autre…
Classic case: You find a new theme or plugin for the WordPress website and all you have to do is install it. Installation usually takes place automatically and without any significant problems. But it can also happen that the new theme or plugin is not compatible.
So before activation, one should make sure that the theme or plugin has been rated well and that it is regularly revised by the developers. Basically, back up your WordPress website before installing so that you can easily restore your data in the event of compatibility problems.
4. Logiciels malveillants et autres effets indésirables
Many may wonder what malware has to do with a WordPress website? Some websites are susceptible to malware and even infected with it, although it’s not clearly recognized.
How can this happen?! For example, by installing an outdated plugin on the WordPress website that is infected with malicious software. If the damaged plugin is now specifically looking for vulnerabilities, then any files could be infected that can no longer be executed properly.
A special circumstance arises with websites: Even if the security hole has been discovered, it may not be 100% fixed. To be on the safe side, we recommend backing up the WordPress website and keeping malware away by restoring the backed up data.
5. Attaque de pirates informatiques, ou : « Il était une fois un site web »
The worst thing that can happen to you with your WordPress website is certainly a hacker attack – a break into the website. For in most cases this means complete loss and/or theft of data. Access to one’s website is often blocked or deactivated by hackers.
In this case, too, your data is irretrievably gone. It actually goes without saying that one can protect the WordPress website in the best possible way with the right security precautions, such as two-factor authentication (2FA). Nevertheless, security loopholes can always occur, which could be misused maliciously.
If you have performed regular backups of your WordPress website, then restoring the backup will help you to get back to your WordPress website with the data, revise the access data and lock the hackers out of the system.
