ESET Remote Administrator supports two types of database servers:

Microsoft SQL Server (including Express and non-Express editions) 2008, 2008 R2, 2012, 2014, 2016

MySQL (5.5+ is supported, we strongly recommend you to use at least version 5.6)

validation-status-icon-error WARNING

MySQL database is supported up to version 5.7 and ODBC driver up to version 5.3.10. Upgrading to a higher version (5.3.11 or 8.x) of MySQL and ODBC driver is not recommended.

Specify the database server you want to use when installing ERA Server or ERA Proxy. Microsoft SQL Server Express is installed by default and is a part of the All-in-one installer. You can use an existing Microsoft SQL Server running in your environment; however, it must meet minimum requirements.

Additional information

Microsoft SQL Server Express has a 10 GB size limit of the each relational database and cannot be installed on a Domain Controller. We do not recommend the use of Microsoft SQL Server Express in Enterprise environments or large networks. If you use Microsoft SBS, we recommend that you install ESET Remote Administrator on a different server or do not select the SQL Server Express component during installation (this requires you to use your existing SQL or MySQL Server to run the ERA database).

If you intend to use the dedicated database user account that will have access to the ERA database only, you must create a user account with specific privileges before installation. For more information, see Dedicated database user account. Additionally, you will need to create an empty database that will be used by ESET Remote Administrator.

ERA Server and ERA Proxy do not use an integrated backup. We strongly recommend that you back up your database server to prevent data loss.
