For the Veeam ONE database, use a server that meets the following requirements:
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:
Size the following tables in accordance with Microsoft SQL Server recommendations:
Other: SSD is recommended for Microsoft SQL Server.
Windows Server 2012 R2 or 2016
Microsoft SQL Server
If you use a virtualized Microsoft SQL Server, this server must run on a separate LUN/datastore from Veeam ONE Server.
* Microsoft SQL Server 2017 is supported by Veeam ONE 9.5 Update 3 or later.
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.
