Database
Specify the database server and connector you want to use when installing the ESET PROTECT Server. You can use an existing database server running in your environment; however, it must meet the requirements below.
The ESET PROTECT On-Prem 11.1 All-in-one installer installs Microsoft SQL Server Express 2019 by default.
oIf you use an earlier Windows edition (Server 2012 or SBS 2011), Microsoft SQL Server Express 2014 will be installed by default.
oThe installer generates a random password for database authentication and stores it in %PROGRAMDATA%\ESET\RemoteAdministrator\Server\EraServerApplicationData\Configuration\startupconfiguration.ini.
|
Microsoft SQL Server Express (the free edition) has a 10 GB size limit for each relational database. We recommend using other Microsoft SQL Server editions than Microsoft SQL Server Express: •In enterprise environments or large networks. •If you want to use ESET PROTECT On-Prem with ESET Inspect On-Prem. |
Supported database servers and database connectors
ESET PROTECT On-Prem supports two types of database servers: Microsoft SQL Server and MySQL.
|
ESET PROTECT On-Prem does not support MariaDB. MariaDB is a default database in most current Linux environments and gets installed when you select to install MySQL. |

Performance recommendations
We recommend using the latest supported Microsoft SQL Server as your ESET PROTECT database for the best performance. While ESET PROTECT On-Prem is compatible with MySQL, using MySQL can negatively impact system performance when working with large amounts of data, including dashboards, detections, and clients. The same hardware with Microsoft SQL Server can handle significantly more clients than with MySQL.
You can decide whether to install an SQL database server on:
•The same machine as the ESET PROTECT Server.
•The same machine, but on a separate disk.
•A dedicated server for the installation of an SQL database server.
We recommend that you use a dedicated machine(s) with reserved resources if you want to manage more than 10,000 clients.

Additional information
|
ESET PROTECT Server does not use an integrated backup. We strongly recommend that you back up your database server to prevent data loss. |
•Do not install SQL Server on a Domain Controller. Install ESET PROTECT On-Prem on a different server or deselect the SQL Server Express component during installation. Use your existing SQL or MySQL Server to run the ESET PROTECT database.
•If you intend to use a dedicated database user account that will only have access to the ESET PROTECT database, you must create a user account with specific privileges before installation. For more information, see the dedicated database user account. Additionally, you will need to create an empty database that will be used by ESET PROTECT On-Prem.
•See the instructions to install and configure MySQL for Windows and MySQL for Linux to work properly with ESET PROTECT On-Prem.
•Microsoft SQL Server on Linux is not supported. However, you can connect the ESET PROTECT Server on Linux to Microsoft SQL Server on Windows.
•If you install the ESET PROTECT Server and Microsoft SQL Server on separate computers, you can enable encrypted connection to the database.
•The cluster setup of the database on Windows environments is supported only for the Microsoft SQL Server, not for MySQL.
