Microsoft SQL Server

In this article

    For the Veeam ONE database, use a server that meets the following requirements:



    CPU, RAM

    CPU and RAM sizing requirements are the same as for the Veeam ONE Server.

    Important! These requirements assume that the Veeam ONE database is hosted on a dedicated Microsoft SQL Server. If the SQL Server is shared by several applications, compute requirements will be higher. To calculate the amount of resources required by other applications, see application-specific sizing recommendations for Microsoft SQL Server.


    Install the OS and Microsoft SQL Server on different drives.

    OS Drive: 50 GB

    Application drive: Use the Veeam ONE Database Calculator to size application data. With partitioning scripts provided at Step 5 of the document, you will have the following distribution of the Veeam ONE database size:

    • Primary Tables: 20%
    • Partitioned Tables: 80%

    Size the following tables in accordance with Microsoft SQL Server recommendations:

    • Primary Logs
    • Partitioned Logs
    • TempDB

    Other: SSD RAID storage with broadband connectivity must be used for the TempDB table.


    Windows Server 2012 R2, 2016, 2019 or 2022

    Microsoft SQL Server

    • Microsoft SQL Server 2014, 2016, 2017 or 2019 Enterprise Edition
    • Microsoft SQL Server Reporting Services 2014, 2016, 2017 or 2019


    If you use a virtualized Microsoft SQL Server, this server must run on a separate LUN/datastore from Veeam ONE Server.

    Database Size

    To calculate an expected size of the Veeam ONE database, use the Veeam ONE Database Calculator. The calculator helps estimate disk space required to store VMware vSphere, Microsoft Hyper-V and Veeam Backup & Replication data.
