Short answer: The most common WordPress backup mistakes include not backing up the database, relying on a single backup location, skipping restore tests, using only manual backups, and failing to verify backup integrity. Avoid these by implementing a comprehensive, automated, and tested backup strategy.
Key takeaways
- Always back up both files and database together.
- Store backups in multiple locations, including offsite.
- Test restores regularly to ensure backups work.
- Automate backups to remove human error.
- Verify backup integrity with checksums or logs.
What you will find here
WordPress backups seem simple. Install a plugin, schedule it, and you’re safe. But small mistakes slip in. The kind you don’t notice until you need to restore. By then, it’s too late. I’ve seen site owners lose weeks of work because their backup was incomplete, corrupted, or just missing. Let’s fix that. Here are five common WordPress backup mistakes and how to avoid them.
1. Backing Up Only Files, Not the Database
Your WordPress site has two parts: files and database. Files contain your themes, plugins, and uploads. The database holds every post, page, comment, and setting. If you only back up files, you lose all your content. A fresh install from files gives you an empty shell.
The fix is simple. Always back up both. Most backup plugins let you choose. Select “complete backup” or both options. If you’re doing a manual backup, export the database via phpMyAdmin and download your wp-content folder. Check out the Beginner’s Guide to WordPress Database Backup for step-by-step instructions.
One common trap: some hosts provide automated backups that only cover files. Verify what your host actually backs up. Ask support. Don’t assume. I’ve seen hosts that say “daily backups” but skip the database entirely. If you rely on that, you’re one restore away from a blank site. Always maintain your own backup system as a safety net.
2. Storing Backups in Only One Location
Keeping backups on your server is convenient. But if your server fails, your backups go with it. Same with a local drive. Hard drives fail, laptops get stolen, and cloud accounts get hacked.
The solution is the 3-2-1 rule. Keep at least three copies of your data, on two different media types, with one copy offsite. For example, one backup on your server, one on an external drive, and one in cloud storage like Google Drive or Dropbox. Many backup plugins can send copies to multiple destinations automatically.
When choosing a remote destination, pick one that supports versioning or file history. This protects against accidental deletion or ransomware. Services like Amazon S3 or Backblaze B2 offer low-cost archival options. For smaller sites, a simple Google Drive or Dropbox folder works. Just enable sync so changes propagate. And set up email notifications so you know when each backup completes — or fails.
3. Never Testing Your Backups
A backup you never test isn’t a backup. It’s hope. I’ve seen plugins report success while creating corrupt files. You won’t know until you try to restore. And that’s the worst time to learn.
Schedule a test restore every month. Restore to a staging site or a local environment. Check that all pages load, images display, and plugins work. If you’re planning a migration, follow the process in How to Back Up a WordPress Site Before Migration – Step by Step. It includes restore testing steps.
Watch for subtle issues. Test contact forms, login pages, and any custom functionality. A backup might restore the content but break a dependency — for example, missing rewrite rules cause 404s. Run a test post submission and verify the email notification arrives. If you use e-commerce, place a test order and confirm the database recorded it correctly. Restoring to a staging environment lets you check without affecting live visitors. Tools like LocalWP or a subdomain staging setup work well.
4. Relying on Manual Backups Alone
Manual backups are fine as a supplement. But life gets busy. You forget. Or you’re traveling and a critical update goes wrong. If your last manual backup is two months old, you lose two months of work.
Automate your backups. Set a schedule that matches your update frequency. For most sites, daily backups are enough. Weekly at minimum. Automated backups run even when you’re asleep. Read Manual vs Automated WordPress Backups: Which Strategy Wins? to decide what fits your workflow.
Here’s what to consider when setting the schedule: if you publish new content daily, backup daily. If you run an e-commerce store with frequent orders, consider multiple daily backups. Choose a time with low traffic — early morning or late night. Most plugins let you set a cron job or use their built-in scheduler. Avoid backing up during high-load periods to prevent site slowdowns. Also, keep at least 7 to 30 days of backup history so you can roll back to a specific point if needed.
5. Ignoring Backup Verification and Integrity Checks
A backup file exists. Great. But is it usable? Corrupted files happen during upload, download, or storage. If you don’t check, you might store a broken backup for months.
Use plugins that verify backups after creation. Look for features like checksum verification or log summaries. Manually, you can check file size changes over time. A backup that’s suddenly smaller might be incomplete. Also, ensure your backup tool reports errors. Don’t just glance at green checkmarks.
Deepen your checks: compare the number of files in the backup archive to what’s on your live server. Use a plugin that logs each step and flags warnings. Some tools, like BackWPup or UpdraftPlus, show you the last backup log. Scan it for entries like “failed to read file” or “timeout reached”. If you see those, investigate immediately. Corrupted database exports often produce zero-byte .sql files. Always confirm your backup archive contains both the .sql file and the files folder. A simple way: restore to a throwaway directory once a quarter and run a diff against your live site’s file list.
How to Select the Right Backup Frequency
Your backup schedule depends on two things: how often your content changes, and how much data you can afford to lose. This is called your recovery point objective (RPO). If you publish one post per week, weekly backups cover you. If you process orders every hour, you need hourly backups.
Here’s a practical guideline: for a typical blog, daily is fine. For an e-commerce site, aim for every six hours during business hours. For a membership site with daily content drops, daily is still okay, but set two copies per day. Use incremental backups to reduce server load — they only save changes since the last full backup. Many plugins offer this. It’s faster and uses less storage. Just be careful: incremental backups require a recent full backup to restore from. If that full backup is corrupt, you’re stuck. So keep a full backup weekly even with daily increments.
Build a Bulletproof Backup Routine
Now you know the mistakes. Avoid them by building a routine: back up both files and database, store copies in at least two offsite locations, automate the process, test restores monthly, and verify every backup. It takes an hour to set up. It saves days of recovery.
Start today. Review your current backup setup. Is it missing anything? Fix one mistake at a time. Your future self will thank you.
Frequently asked questions
How often should I back up my WordPress site?
For most sites, daily backups are ideal. If you update content weekly, a weekly backup may suffice. E-commerce or high-traffic sites should back up every few hours. The key is to match the backup frequency to how often your site changes.
What files should be included in a WordPress backup?
A complete backup includes your WordPress database and all files: wp-content folder (themes, plugins, uploads), wp-config.php, and .htaccess. Excluding any of these can make restoration impossible or incomplete.
Do I need to stop my site during backup?
It depends. Most plugins handle backups without downtime. But for large sites on shared hosting, a backup can temporarily slow performance. Consider scheduling backups during low-traffic hours or using a host that supports snapshot backups without impact.
Can I use a free backup plugin?
Yes, many free plugins like UpdraftPlus and BackWPup offer reliable backups. They often limit features like offsite storage or scheduling. For most small to medium sites, they work fine. Just ensure the plugin is actively maintained and tested with your WordPress version.
What is the best way to store backups offsite?
Cloud storage services like Google Drive, Dropbox, or Amazon S3 are popular. Some backup plugins can send backups directly to these. Alternatively, download backups to a local external drive. The goal is to keep a copy separate from your server.
