Duplicator Pro lets you migrate, duplicate, move, or backup an entire WordPress site from one location to another. It packages your entire site — database, themes, plugins, media, and settings — into a single archive file, then provides an installer script that runs the migration on the destination server. Unlike plugins that require WordPress to be running on the destination to restore, Duplicator’s installer works on a clean server with no existing WordPress installation. This makes it the go-to plugin for moving sites between hosts, creating staging copies, or duplicating a production site to a development environment. For migrating single sites, it competes directly with All-in-One WP Migration Pro, though Duplicator’s installer-script approach gives it an edge on more complex migrations.
The Pro version adds scheduled backups with cloud storage to Dropbox, Google Drive, Amazon S3, and other destinations, plus email notifications and database-only backups.
Competitive Features
- Drag-and-drop installer — installer script works on any server with PHP, no existing WordPress required
- Scheduled backups — automatic daily, weekly, or monthly backups with configurable retention
- Cloud storage — store backups on Dropbox, Google Drive, Amazon S3, OneDrive, and FTP
- Database-only backups — backup just the database for quick exports without file overhead
- Multisite support — full backup and migration support for WordPress multisite networks
- Server-to-server import — direct transfer between servers without local file download
- Email notifications — backup completion and failure alerts sent to configured recipients
Key Features
- Archive packaging — creates a zip or daf archive with your entire site, including file exclusions and filters
- Installer script — standalone PHP script that runs the migration: database import, URL replacement, and file extraction
- Serialized data handling — safely replaces serialized URLs in the database without corruption
- Scheduled backups — automated backups with flexible scheduling, retention policies, and cloud destination
- Archive validation — tests archive integrity after creation and before restore to verify backup quality
- File and database filters — exclude specific file types, directories, or database tables from backups
- WP-CLI support — command-line interface for backup creation and site duplication
Comparison with Competitors
Duplicator Pro vs All-in-One WP Migration Pro
| Aspect | Duplicator Pro | All-in-One WP Migration Pro |
|---|---|---|
| Installer approach | Standalone script (installer.php) | Import within WP admin |
| Requires WP on destination | No | Yes |
| Scheduled backups | Yes | Yes |
| Cloud storage | 6+ destinations | 10+ destinations |
| Multisite | Yes | Via extension |
| Archive format | Zip, DAF | .wpress (proprietary) |
Bottom line: All-in-One WP Migration Pro processes in 512KB chunks, making it more reliable on shared hosting. Duplicator Pro’s standalone installer can restore sites without WordPress going first, which is preferable for complex migrations or recovery scenarios.
Duplicator Pro vs UpdraftPlus Premium
| Aspect | Duplicator Pro | UpdraftPlus Premium |
|---|---|---|
| Primary use | Migration + backup | Backup + restore |
| Site migration | Yes (installer.php) | Yes (manual steps) |
| Cloud storage | 6 destinations | 15+ destinations |
| Multisite | Yes | Yes |
| Database backup | Yes | Yes |
| Staging | No | Yes |
Bottom line: UpdraftPlus Premium is stronger for ongoing scheduled backups with more cloud destinations. Duplicator Pro is better for site migrations with its standalone installer that works without a running WordPress instance.
Recommended Stack: Duplicator Pro handles site migration and scheduled backups. For monitoring link health after migration, use Broken Link Checker Pro to automatically detect and fix broken URLs across your migrated site.

Frequently Asked Questions
Can Duplicator migrate a site without existing WordPress?
Yes. The installer script (installer.php) runs independently of WordPress. You upload the archive and installer to a new server, navigate to the installer URL, and walk through the migration wizard. No WordPress needs to be installed first.
Does Duplicator work on shared hosting?
Yes. Duplicator can process backups in smaller chunks to stay within PHP memory limits on shared hosting. The installer script also works within typical shared hosting constraints.
Does Duplicator support scheduled backups?
Yes. The Pro version includes scheduled backups with customizable intervals (hourly, daily, weekly, monthly) and automated cloud storage uploads. The free version only supports manual one-time backups.
Can I exclude specific files from the backup?
Yes. Duplicator includes file filters where you can exclude specific directories, file types, or individual files from the archive. Database table filters let you exclude specific tables from the database backup.
How does Duplicator handle serialized data?
Duplicator uses a custom serialized data replacement engine that safely updates serialized PHP arrays during URL replacement. This prevents the data corruption that can occur when using simple search-and-replace on serialized WordPress data.
