If you want to use your extension as a primary Backup feature, go to the MainWP > Settings page. In the Backup Options box, locate the Select Primary Backup System option, and from the dropdown, select the MainWP UpdraftPlus Extension.

Setting the UpdraftPlus as a primary backup option as primary will make some changes to your dashboard.

1. The Backup Now link in the Manage Sites page will replace the extension’s Backup Now link.
2. The Schedule Backup link in the MainWP menu will be replaced with the Existing Backups link, which leads to the extension page, where you can see all your backups.
3. The original backup settings from the MainWP > Settings page will be removed.
