WordPress Backup
What a complete WordPress backup includes, how often to run one, where to store it, and how to test restores so a failed update or hack is easy to undo.
What Is a WordPress Backup?
A WordPress backup is a restorable copy of the two things that make up a WordPress site: the database, which holds posts, pages, settings, users and orders, and the files, chiefly the wp-content folder with uploads, themes and plugins, plus wp-config.php. A backup is only complete if both parts are captured from the same point in time and can be put back together.
Backups can be taken by the host at the server level, by a WordPress plugin, by an external service connecting over SFTP or an API, or by a developer using tools such as WP-CLI's wp db export. The method matters less than three questions: is everything included, is a copy stored somewhere other than the website's own server, and has anyone proved it can be restored?
Why WordPress Backups Matter
A backup is the last line of defence when everything else has failed.
- Failed updates: A plugin or theme update that breaks the site can be rolled back in minutes instead of debugged under pressure.
- Security incidents: Restoring a clean copy from before an infection is often the fastest route back, once the entry point is closed. See WordPress security.
- Human error: Deleted pages, overwritten content and accidental bulk edits happen on every busy site.
- Hosting failures: Hardware problems, billing disputes or an account suspension can remove access to the server entirely.
- Transaction data: On WooCommerce stores, orders and customer accounts change constantly, and losing even a day can create accounting and customer service problems.
Key Components of a WordPress Backup Strategy
- Full scope: The complete database and the files that are not reproducible from elsewhere, especially uploads, custom themes, custom plugins and configuration.
- Frequency matched to change: Daily backups suit most business sites; stores and busy membership sites need more frequent or real-time database backups.
- Off-site storage: At least one copy in separate cloud storage under different credentials, following the familiar 3-2-1 approach: three copies, two different storage types, one off-site.
- Retention: Several weeks of history, so a problem discovered late, such as a hidden infection, can still be rolled back to a clean point.
- Security: Encrypted backup files and restricted access, because backups contain the same personal information as the live site.
- Restore procedure: A documented, tested way to restore the whole site, a single file or just the database, ideally to a staging environment first.
Common WordPress Backup Mistakes
- Keeping backups only on the same server: If the server or hosting account is lost or compromised, the backups go with it.
- Backing up the database but not uploads: Content returns but every image and PDF is missing.
- Never testing a restore: Corrupted archives, missing tables or expired storage credentials are discovered at the worst possible moment.
- Too little retention: Keeping only the last few days means every copy may already contain the problem.
- Restoring over a live store blindly: Rolling back a WooCommerce database wipes any orders placed since the backup was taken.
Best Practices for WordPress Backups
- Combine host and independent backups: Host snapshots are convenient, but keep a second copy the host does not control.
- Take a manual backup before big changes: Before major updates, migrations or redesigns, even if automated backups exist. Make this part of your WordPress maintenance routine.
- Test restores on a schedule: Restore to staging every quarter and check pages, media, forms and logins.
- Think about privacy and location: Backups contain personal information subject to PIPEDA, and Quebec's Law 25 adds requirements for transferring personal information outside Quebec, so know which country your backups are stored in.
- Write down who does what: Record where backups live, how to access them, and who is authorized to restore.
WordPress Backup at PerfectPixels
For the sites we build and maintain, we set up automated, encrypted off-site backups alongside the host's own snapshots, sized to how often the site changes, and we test restores to staging rather than assuming they work. Before any major update or migration we take a fresh backup, and on WooCommerce stores we plan rollbacks so recent orders are not lost. This is included in our WordPress development and maintenance work.
Frequently Asked Questions
Doesn't my host already back up my site?
Many hosts do, but check how often, how long backups are kept, whether they are stored off the server, and whether restoring is free. Host backups are also tied to your account, so if that account is suspended or compromised you may lose access. An independent copy covers that gap.
How often should I back up my WordPress site?
Match frequency to how much you could afford to lose. A brochure site that changes weekly may be fine with daily backups, while an online store taking orders all day needs database backups every hour or in real time.
What is the difference between a backup and staging?
Staging is a working copy of your site for testing changes before they go live. A backup is a stored snapshot used for recovery. You need both, and staging is the safest place to test that a backup actually restores.
