How to Back Up WordPress to Object Storage

This guide walks you through backing up a WordPress site to object storage (like Amazon S3, DigitalOcean Spaces, or Backblaze B2). You’ll learn how to automate the process so your database and files are safely stored off-site, protecting you from server failures, hacks, or accidental deletions. No advanced coding is needed—just a plugin and a few settings.

What You’ll Need

  • A WordPress site with admin access.
  • An object storage account (S3-compatible or native) with your chosen provider.
  • API credentials (Access Key and Secret Key) from your storage provider.
  • A bucket (or container) created in your object storage account.
  • An FTP/SFTP client (like FileZilla) or cPanel file manager for manual checks if needed.

Step-by-Step

  1. Create a bucket in your object storage account. Log in to your provider’s dashboard, navigate to the storage section, and create a new bucket. Choose a region close to your server for faster transfers. Name it something like mywordpress-backups. Note the bucket name and region.
  2. Generate API credentials. In your storage provider’s dashboard, go to API keys or Access Keys. Create a new key pair. Save the Access Key ID and Secret Access Key in a secure place—you won’t be able to see the secret again.
  3. Install a backup plugin. In your WordPress admin, go to Plugins > Add New. Search for a backup plugin that supports remote storage, such as UpdraftPlus, BackupBuddy, or WPvivid. Install and activate one. (This guide uses UpdraftPlus as an example, but the steps are similar for others.)
  4. Configure the plugin’s remote storage settings. Go to the plugin’s settings page (usually under Settings > UpdraftPlus Backups). Click on the Settings tab, then find the Remote storage section. Select your storage provider from the dropdown (e.g., Amazon S3, DigitalOcean Spaces, or generic S3-compatible).
  5. Enter your API credentials and bucket details. For each provider, you’ll need to enter the Access Key, Secret Key, and bucket name. If you’re using an S3-compatible provider like DigitalOcean Spaces, you may also need to enter the endpoint URL (e.g., https://ams3.digitaloceanspaces.com). Fill in the fields exactly as provided by your storage provider.
  6. Set up a backup schedule. In the same settings page, choose how often to back up your files and database. For most sites, a daily database backup and a weekly file backup are reasonable. Set the retention number (how many backups to keep) to avoid cluttering your bucket—e.g., keep 4 weekly backups.
  7. Run a manual backup to test the connection. Go to the Backup / Restore tab in the plugin. Click the Backup Now button. Make sure both database and files are checked. Start the backup. Watch the progress bar—it will upload to your object storage once complete.
  8. Verify the backup in object storage. Log in to your storage provider’s dashboard and open the bucket. You should see a folder with your site’s name containing backup files (e.g., .zip files and a database .gz file). If the files are there, your setup works.
  9. Set up automatic backups. If the manual backup succeeded, the schedule you configured will handle future backups automatically. You can also set up email notifications so you know when backups complete.
  10. Test a restore (optional but recommended). To be fully confident, try restoring your site to a staging environment using the plugin’s restore feature. This ensures your backups are actually usable.

Common Mistakes

  • Using the wrong endpoint URL for S3-compatible providers. This causes connection failures. Always copy the exact endpoint from your provider’s dashboard.
  • Mis-typing the bucket name—bucket names are case-sensitive and must match exactly.
  • Forgetting to set a retention policy—your bucket will fill up with old backups, increasing costs.
  • Not testing the backup—a backup that hasn’t been restored is not a backup.
  • Storing credentials in plain text—never share your API keys; keep them secure.

Tips

  • Use a dedicated bucket for backups and enable versioning on it to protect against accidental overwrites.
  • If your site is large, consider excluding non-essential files (like cache folders) to speed up backups.
  • Schedule backups during off-peak hours to minimize server load.
  • Enable encryption on your backups if your plugin supports it, for extra security.
  • Keep a copy of your API keys in a password manager, not in your WordPress site.

Troubleshooting

  • Connection fails: Double-check your endpoint URL, Access Key, and Secret Key. Ensure your bucket name is correct. Some providers require the region to be included in the endpoint.
  • Backup completes but files are not in the bucket: Check the plugin’s log for upload errors. The issue is often a permission problem—make sure your API key has write access to the bucket.
  • Backup times out: If your site is large, the backup may exceed the server’s execution time. Increase the PHP memory limit and max execution time in your WordPress configuration, or use a plugin that supports chunked uploads.
  • Restore fails: Ensure your backup files are complete. If you’re restoring to a different server, you may need to update the site URL in the database.

Frequently Asked Questions

Can I use any object storage provider?

Most backup plugins support Amazon S3 and S3-compatible providers (like DigitalOcean Spaces, Linode, or Wasabi). Check your plugin’s documentation for the list of supported providers.

Do I need to back up both files and database?

Yes. Your database contains posts, pages, and settings, while files include themes, plugins, and uploads. Both are needed for a full restore.

How often should I back up?

For a busy site, daily database backups and weekly file backups are a good start. Adjust based on how often you update content.

Will backups slow down my site?

Backups can use server resources, but most plugins allow you to set a schedule during low-traffic times. They also use throttling to avoid overwhelming the server.

Can I restore a backup to a different host?

Yes, as long as you have the backup files and the plugin’s restore feature. You’ll need to install WordPress and the plugin, then upload the backup files.

What if my object storage account is hacked?

Use strong, unique API keys and enable multi-factor authentication on your storage provider account. Also, consider encrypting your backups.
