The vSphere Replication appliance contains an embedded vPostgreSQL database that you can use immediately after you deploy the appliance, without any additional database configuration. If necessary, you can reconfigure vSphere Replication to use an external database.

Each vSphere Replication appliance requires its own database. If the database at either site is corrupted, vSphere Replication does not function. vSphere Replication cannot use the vCenter Server database because it has different database schema requirements. However, if you do not use the embedded vSphere Replication database, you can use the vCenter Server database to create and support an external vSphere Replication database.

You might need to use an external database to improve performance or load balancing, for easier backup, or to meet your company's database standards.

Note: vSphere Replication server inside the vSphere Replication appliance uses its own embedded database and config files. Configuring VRMS to use external database does not provide protection of losing the vSphere Replication appliance or any additional vSphere Replication Server appliance.

If you reinitialize the database after you deploy vSphere Replication, you must go to the vSphere Replication virtual appliance management interface (VAMI) to reconfigure vSphere Replication to use the new database connection.


  • Verify that the vSphere Replication appliance is powered on.
  • Verify that you have administrator privileges to configure the vSphere Replication appliance.
  • You must create and configure the external database before you connect it to vSphere Replication. See vSphere Replication Supported Databases for the configuration requirements for each supported type of database.


  1. Use a supported browser to log in to the vSphere Replication VAMI.
    The URL for the VAMI is https:// vr-appliance-address:5480.
  2. (Optional) Review and confirm the browser security exception to proceed to the login page.
  3. Enter the root user name and password for the appliance.
    You configured the root password during the OVF deployment of the vSphere Replication appliance.
  4. On the VR tab, click Configuration.
  5. Select Manual configuration to specify a configuration or select Configure from an existing VRM database to use a previously established configuration.
  6. In the DB text boxes, provide information about the database for vSphere Replication to use.
    Option Setting
    DB Type Select SQL Server or Oracle.
    DB Host IP address or fully qualified domain name of the host on which the database server is running.
    DB Port Port on which to connect to the database.
    DB user name User name for the vSphere Replication database user account that you create on the database server.
    DB Password Password for the vSphere Replication database user account that you create on the database server.
    DB Name Name of the vSphere Replication database instance.
  7. (Optional) Select the Show DB URL check box.
    Advanced users can fine-tune other database properties by modifying the URL, for example if you use a named instance of SQL Server.
  8. Click Save and Restart Service to apply the changes.


You configured vSphere Replication to use an external database instead of the database that is embedded in the vSphere Replication appliance.
