Introduction

Database’s Replicas ensure the security of your data: a Replica is a separate Database in another Project that follows the primary Database. You can create up to 5 Replicas of a Database in different Projects of the same region as the primary Database.

Replicas are available for PostgreSQL, TimescaleDB, MySQL, MariaDB and Redis. The REPLICAS TAB is not shown for MongoDB.

A Replica follows its primary Database: its databases, extensions, settings and custom options come from the primary and cannot be changed on the Replica, and the password of its main user cannot be reset there.

Create and delete Replica

The REPLICAS TAB of the Database details page lists the Replicas (Name, Status, Mode, Version, Created); click the name of a Replica to open it in its own Project.

• Create. Click CREATE REPLICA, select the Project (only Projects of the same region are offered, the current one is marked (Current project)) and click CREATE. The button is active only while the primary Database is running (ACTIVE or DEGRADED), is not itself a Replica and has fewer than 5 Replicas. The Replica appears with the PROVISIONING status (then ACTIVE), the primary Database changes its Mode from Standalone to Primary, and in the selected Project the new Database is listed in the Replica mode.
• Delete. Use Delete in the row Actions menu on the REPLICAS TAB, or in the Actions menu of the Replica on the Databases page of its Project, and confirm.
