A faulty update, a corrupted database, a compromised WordPress plugin, human error, or a technical failure can be enough to partially or completely cripple a website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At this moment, it no longer matters whether a backup exists somewhere. What is decisive is, <strong>whether the website can actually and in a reasonable time be restored from it.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is precisely the difference between a simple data backup and a well-thought-out backup and disaster recovery strategy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does disaster recovery mean for a website?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Disaster Recovery refers to the measures used to restore systems and data to a functional state after a severe failure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On a website, such an incident can be caused, for example, by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hardware or storage failures<\/li>\n\n\n\n<li>faulty WordPress or plugin updates<\/li>\n\n\n\n<li>damaged databases<\/li>\n\n\n\n<li>Malware or compromised websites<\/li>\n\n\n\n<li>accidentally deleted files<\/li>\n\n\n\n<li>Misconfigurations<\/li>\n\n\n\n<li>Issues with the hosting provider<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">While a backup is an important component, it is not yet a complete disaster recovery strategy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Backup and disaster recovery are not the same<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Initially, a backup only answers the question: <strong>Is there a copy of my data?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Disaster Recovery goes a step further: <strong>How do I turn this copy back into a working system?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a WordPress website, for example, it is not enough to just back up the uploaded images. For a complete restoration, the WordPress files and the database, among other things, are required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the environment, configurations, DNS settings, SSL certificates, or other components are also added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the most important question is not: \u201eDo we have backups?\u201c<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather: <strong>\u201eCan we reliably restore our website from these backups?\u201c<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why a backup on the same system can be problematic<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A backup only provides protection if it is sufficiently independent of the original system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the only backup is, for example, on the same server as the productive website, a major failure can affect both at the same time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same applies to compromised systems: if an attacker gains extensive access, locally stored backups may also be affected under unfavorable circumstances.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a well-thought-out backup strategy takes into account the separation between the production system and the backup.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The 3-2-1 rule as a guide<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A well-known basic rule for data backups is the so-called <strong>3-2-1 backup rule<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simplified, it means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>3 copies<\/strong> of the important data<\/li>\n\n\n\n<li>on <strong>2 different storage media or systems<\/strong><\/li>\n\n\n\n<li>at least of which <strong>1 copy separated from the primary location<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Not every small website necessarily needs a complex enterprise backup infrastructure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the basic principle remains sensible: <strong>The backup must not be susceptible to the same error as the original.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How often should a website be backed up?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The correct backup frequency depends on how often a website's data changes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a largely static club or informational website, a different strategy may make sense than for a heavily trafficked WooCommerce store.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, an online shop continuously changes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Orders<\/li>\n\n\n\n<li>Customer accounts<\/li>\n\n\n\n<li>Inventories<\/li>\n\n\n\n<li>Payment information and status data<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The more data generated between two backups, the greater the potential loss during a recovery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">RPO and RTO: Two terms that describe the actual risk<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Professional backup concepts often use two key metrics: <strong>RPO<\/strong> and <strong>RTO<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">RPO \u2013 Recovery Point Objective<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Simply put, the RPO describes how much data loss would be acceptable in the worst-case scenario.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If backups are made once a day, for example, changes made since the last backup could theoretically be lost.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a simple website, that may be acceptable. For an active online store, perhaps not.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">RTO \u2013 Recovery Time Objective<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The RTO describes the maximum allowable downtime for a system before it should be restored.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here too, the requirements vary considerably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A private website may be offline for a few hours or longer. For a mission-critical online store, even a short downtime can cost sales.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why multiple backup versions are important<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A single current backup is not always enough.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The problem: An error or compromise may have already gone unnoticed for several days.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If only a single backup is overwritten daily, the backup itself may eventually contain the corrupted or compromised state.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Versioned backups, on the other hand, make it possible to revert to an older state.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why multiple restore points are an important part of a good backup strategy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A backup is only as good as its restore<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most common mistakes is having backups created automatically, but never checking whether they can actually be used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A successful backup message does not automatically mean that a complete website can be restored from it without errors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, backup systems and recovery processes should be reviewed regularly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can find more basics on this in our guide: <a href=\"https:\/\/www.curiaweb.ch\/en\/backup-strategies-smes\/\"><strong>Backup Strategies: What Really Matters<\/strong><\/a> .<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">WordPress has special requirements for backups<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress does not consist only of files. A large part of the website is located in the database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, lying there are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Posts and pages<\/li>\n\n\n\n<li>User accounts<\/li>\n\n\n\n<li>WordPress settings<\/li>\n\n\n\n<li>Plugin configurations<\/li>\n\n\n\n<li>WooCommerce Data<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A complete WordPress backup must therefore include both files and the database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A current restore point is especially important right before major updates or changes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What happens when a WordPress site is hacked?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the event of a security incident, recovery is more complex than after an accidentally deleted file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simply restoring the last backup can be problematic if it already contains malicious code or if the original security vulnerability still exists.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First, it must therefore be clarified:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How was the website compromised?<\/li>\n\n\n\n<li>Since when has the attack been ongoing?<\/li>\n\n\n\n<li>Which recovery point is still clean?<\/li>\n\n\n\n<li>Has the original vulnerability been patched?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">We explain more about this in the article: <a href=\"https:\/\/www.curiaweb.ch\/en\/wordpress-gehackt-was-jetzt\/\"><strong>WordPress hacked \u2013 what now?<\/strong><\/a> .<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hosting backup and additional website backup<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A hosting backup and an additional, separate website backup do not necessarily fulfill the same purpose.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The hosting backup typically serves for restoration within the existing hosting environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An additional backup solution, on the other hand, can create another independent backup layer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether such additional security is necessary depends on the value and criticality of the website.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">CodeGuard as an additional backup layer<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For websites where an additional backup separate from the actual web hosting is desired, an external backup solution can be useful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CURIAWEB offers this, among other things, <strong>CodeGuard<\/strong> a.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CodeGuard can regularly back up websites independently of the actual hosting and monitor changes. This creates an additional backup layer that is not solely dependent on the web hosting's backup infrastructure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is interesting, for example, if a website is hosted by a different provider or if an additional backup is desired for a particularly important website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More information: <a href=\"https:\/\/www.curiaweb.ch\/en\/codeguard-backup\/\"><strong>CodeGuard Website Backup<\/strong><\/a> .<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does data protection have to do with backups?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Backups may contain personal data. Therefore, they must be taken into account in a data protection concept just like productive systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Relevant, among other things, are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Access protection<\/li>\n\n\n\n<li>Retention period<\/li>\n\n\n\n<li>Storage location<\/li>\n\n\n\n<li>Protection against unauthorized access<\/li>\n\n\n\n<li>Deletion and recovery processes<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a data backup is not automatically a complete data protection measure. It is a component of a more comprehensive technical and organizational security concept.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What happens if the entire hosting provider goes down?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This question is also part of a realistic risk analysis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Anyone who is completely dependent on a single vendor, a single access point, and a single backup infrastructure should at least know how to access their own data in an emergency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, for mission-critical websites, an additional backup independent of the hosting provider can be useful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In extreme cases, this also makes it possible to restore a website in a different hosting environment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A hosting change can be part of the emergency strategy<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If persistent problems with performance, stability, security, or support arise, you should not wait for a complete failure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A controlled hosting change is significantly easier than a migration under time pressure during an emergency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CURIAWEB migrates existing websites for new customers free of charge when switching.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Read more: <a href=\"https:\/\/www.curiaweb.ch\/en\/hosting-change-free-migration-service\/\"><strong>Hosting change with free migration service<\/strong><\/a> .<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which backup strategy is the right one?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is no backup strategy that has to be identical for every website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A sensible solution is based on the actual risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In particular, the following questions should be answered:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How important is the website for me or my organization?<\/li>\n\n\n\n<li>How often do the data change?<\/li>\n\n\n\n<li>How much data loss would be acceptable?<\/li>\n\n\n\n<li>How long would the website be allowed to be down?<\/li>\n\n\n\n<li>How many older restore points do I need?<\/li>\n\n\n\n<li>Where are the backups located?<\/li>\n\n\n\n<li>Can the website also be restored on a different infrastructure?<\/li>\n\n\n\n<li>Has the recovery already been tested?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A small personal website, a club website, a corporate site, and a WooCommerce shop can therefore have completely different requirements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion: It's not the backup that counts, but the restorability<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Backups are among the most essential foundations of reliable website operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the crucial question is not whether a backup exists somewhere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The crucial part is, <strong>whether the correct data is being backed up, how up-to-date the backups are, and whether a functioning website can be restored from them in an emergency.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A good disaster recovery strategy therefore considers not only backups, but also recovery times, versioning, independence from the production system, and regular testing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The more important a website is, the less its recovery should be left to chance.<\/p>","protected":false},"excerpt":{"rendered":"<p>A backup alone is not enough in an emergency.
