wordpress automatic backup: if you're here, it's because you want backups that are reliable, regular and, above all, invisible to performance. Very good. The most common trap is to back up well... but at the wrong time, with the wrong tool, on the wrong storage - and then discover that the site slows down, admin becomes a pain, or the restore is incomplete. The aim of this article is to give you a clear method for automating your backups without impacting your response time, while maintaining a solid restoration plan.
Avoiding site-losing backups: common causes
A slowdown during backups is not inevitable: it is almost always linked to the way the backup is executed (CPU/IO load, massive SQL queries, heavy compression, network transfers) and to its triggering (wrong schedule, too frequent, no incremental). Here are the problem scenarios:
1) Too frequent full backups every hour, a complete archive (files + database) has to be reread and recompressed for thousands of files, and a sometimes voluminous database has to be dumpered, even if 99% hasn't changed.
2) Compression and encryption on the server zip/tar + encryption consumes CPU and causes peaks. On shared hosting, this is even more visible (resource limits, throttling).
3) Transfer to a cloud at the wrong time Uploading a heavy archive can saturate outgoing bandwidth, disrupt TTFB, and slow down downloads on the visitor's side if the hosting doesn't properly isolate the traffic.
4) Noisy database table logs, sessions, cache tables, statistics tables, SEO or security tables. Including them in each dump increases the size of the database, the number of locks and the extraction time.
5) Wrongly triggered WordPress cron WP-Cron depends on visits; on a low-traffic site it may not run at the right time, and on a high-traffic site it may be triggered too often (and overlap) if badly configured.
Choosing the right strategy: incremental, outsourced and restoration-oriented
If your priority is not to slow down the site, first look for an approach that reduces the work on the WordPress server. Ideally, you combine :
1) Incremental backup : only what has changed since the last backup is copied. This is the most efficient way of reducing the CPU/IO footprint and the volume transferred.
2) Off-peak performance In practice, early in the morning (depending on your audience) and avoiding the hours of marketing/newsletter campaigns.
3) External storage Your backups must not live on the same server as your site. In the event of hacking or disk failure, you'll lose everything.
4) Restoration tests A backup is only valuable if you can restore it quickly and cleanly, while preserving the site's integrity (media, database, users, settings, plugins, theme).

Automatic backup plan recommended (no significant impact)
1) Define frequency according to actual risk
The frequency should reflect your tolerance to data loss (RPO). Example:
Showcase site Daily (or even 2-3 times a week) if content changes little.
Active blog daily + backup before major update.
E-commerce / booking / membership This can be done several times a day (or even hourly), but ideally incrementally, with an intelligently processed database (no unnecessary tables).
2) Separate files and databases
To limit the load, do not treat files + base as a single block each time:
Database This is where orders, accounts and recent content live.
Files (uploads, theme, plugins): less frequent if the site changes little, or incremental if possible.
In practical terms, a successful schedule often looks like this: base every X hours (depending on activity), files once a day, and a weekly full restore point.
3) Exclude what should not be saved
To accelerate, you need to reduce the surface area. Examples of exclusions (depending on your stack):
Directories caches (cache plugin, image cache), log folders, old backups, temporary folders.
Tables You'll be able to easily regenerate these tables of non-essential statistics, security logs, sessions and transients.
Warning: never exclude at random. We exclude what we know how to rebuild (cache), not what carries the value (orders, media, content).
4) Use a reliable trigger (avoid overlapping)
A slow site during backups is often the result of overlapping processes: a backup is launched while the previous one is still running, or during a heavy task (optimization, cron, import, image generation).
To stabilize :
Limit to 1 backup at a time (verrou/lock).
Scheduling via system cron rather than WP-Cron if possible.
Avoid maintenance hours (automatic updates, marketing tasks, exports).
Plugins vs. backups on the hosting side: what's best for performance?
The right choice depends on your context, but in terms of speed, the order of preference is often :
1) Host-level backup (snapshots) restore: often the fastest, as it's close to storage (and sometimes outside your CPU quota). On the other hand, granularity (restoring a single file) and portability (migrating elsewhere) can be limited.
2) Outsourced/incremental backup solution designed to limit the load and speed up restoration.
3) Classic full archive plugin : can work very well on a small site, but quickly becomes cumbersome as uploads and base grow.

Concrete settings to avoid slowing down WordPress during backups
Limit CPU/IO consumption
If your tool offers settings, give preference to :
Incremental rather than complete.
Moderate compression (or destination-side compression where possible).
Cutting into pieces (chunks) to avoid large monolithic files and PHP timeouts.
Throttling (rate limiting) when uploading to external storage, especially if you have traffic peaks.
Intelligent media management (uploads)
Images/videos often represent the largest volume. To avoid saving gigabytes unnecessarily:
Incremental files (if available).
Do not rezip all wp-content/uploads on every pass.
On very large sites Backup: consider a strategy where media already live on external storage (depending on your architecture), reducing the pressure on conventional backups.
Monitoring admin: a load indicator
When backups are set up incorrectly, one of the first symptoms is a sluggish administration interface, especially when running scheduled tasks (cron) and accessing the dashboard.
If you observe this phenomenon, this diagnostic can help you link performance and background tasks: Slow in Admin Technical Causes.
Catering: the real test (and how to make it fast)
Many sites back up, but restore badly: incomplete archive, inconsistent database, missing files, or restoration that breaks URLs, permalinks or even SSL. For a fast, reliable restore:
1) Keep several points minimum 7 to 30 days, depending on your activity. A hack can remain invisible for several days; if you only have 2 backups, you could be stuck.
2) Maintain rotation daily + weekly + monthly, to go back further in the event of a latent problem.
3) Test on a pre-production Once a quarter (at least), restore to a staging environment. You check: admin login, key pages, forms, purchase tunnel, transactional emails.
4) Document the procedure Where are the backups, who has access, how to restore, how long does it take, and what to check afterwards.
Before updates: automate a painless restore point

Updates (core, theme, plugins) are a major cause of breakage. Best practice: automatically trigger a backup just before a high-risk update, then launch the update. This avoids endless manual backtracking.
This logic fits naturally into a regular maintenance routine. To structure it properly : How to set up effective monthly maintenance.
Beware of plugins: some choices degrade performance and reliability
Not all backup plug-ins are created equal. Some perform cumbersome tasks via PHP, create gigantic archives, store locally for too long, or lack anti-timeout mechanisms. Others conflict with caching plugins, security plugins or hardened environments.
Conversely, a correct solution :
Manages large sites (chunking, error recovery).
Supports external storage and automatic rotation.
Offers guided restoration (or at least a clear procedure).
Diary errors and alerts you.

Special cases: e-commerce, multilingual sites, redesigns
E-commerce (WooCommerce)
In a store, the database is constantly changing: orders, baskets, customers, stock. A daily file + database backup may not be enough if you don't want to lose recent orders. Prefer a more frequent database (even several times a day) and check that large, non-critical tables don't artificially inflate your dump.
Multilingual sites and heavy content
Database volume can explode (translations, custom fields, builders). Incrementality and the exclusion of non-essential tables are key to keeping backup windows short.
After an overhaul
A redesign often creates: new media, new plugins, caches, redirects, additional tables. Immediately after going live, you need a tighter strategy (close restoration points) and an eye on performance, as the overall weight of the site changes rapidly.
To avoid accumulating technical debts and cumbersome backups: Optimize After Redesign.
Security and compliance: encrypted backups, access and retention
Not slowing down the site should not be at the expense of safety:
Encryption Wherever possible, encryption on the storage side (or tool side) without overloading the server. For certain contexts, destination-side encryption is more efficient.
Access Restrict the number of accounts that can download/restore; enable 2FA on storage consoles.
Retention Keep the duration in line with your business needs (and legal constraints if applicable), but avoid infinite accumulation, which increases costs and complexity.
When to delegate: saving time without losing control
Automating reliable, monitored and tested backups, with rotation and fast restores, is more than just installing a plugin. It also means checking logs, correcting failures, adjusting exclusions and validating restores. This is precisely what many teams don't have the time to do on a regular basis.
If you're on the fence between managing everything in-house and outsourcing, this content will help you decide: Why entrust maintenance to an agency?.
Final checklist: fast and really useful automatic backups
1) External storage (never only on the server).
2) Incremental as soon as the site exceeds a few hundred MB or the database grows.
3) Frequency aligned with your RPO (showcase ≠ e-commerce).
4) Controlled exclusions (caches/logs yes, vital data no).
5) Anti-climbing (one backup at a time).
6) Rotation + retention (daily/weekly/monthly).
7) Restoration tests sur staging, on a regular basis.
8) Alerts in case of failure (e-mail/notification).
9) Backup before updates (automatic if possible).
10) Quarterly magazine The strategy must evolve with the site.
