Installing Zerto Virtual Replication : Database Requirements
  
Database Requirements
During the Zerto Virtual Manager installation, the user is able to select whether to install and use an embedded SQL Server (localdb) as the database.
Alternatively, and also during the installation, the user is able to choose whether to instead select and use an external SQL Server instance. To use an externally managed database, during the installation select the Custom Installation option.
The larger the environment protected by Zerto Virtual Manager, the larger the database size required to support it.
Supported Microsoft SQL Server versions: 2008, and higher.
