Duplicator allows you to make a copy of your WordPress files and database and quickly move it to another location. It saves you significant time when you want to install the same theme, plugins or content on different sites. By converting a WordPress installation configured on a single site into a Duplicator package, you can create any number of pre-configured sites.

In addition to the standard single site feature, Duplicator Pro supports multi-site network backup and migration. It even allows you to create a site as an independent sub-site. It also supports very large databases, making it easy to manually import SQL files.

Duplicator also offers the possibility to set backup limits. This prevents your services, such as Dropbox, from filling up with too many backups and helps you keep unnecessary backups clean. It also allows you to filter only the directories, files, extensions and database tables you want to back up.

The plugin also has useful features such as automatic database creation, email notifications and support for larger packages. You can also customise backup and installation processes using advanced options. This way, you can have more control over the backup and migration process.
