Before You Begin

In this article

Before you install Veeam Backup & Replication, check the following prerequisites:

The machine on which you plan to install Veeam Backup & Replication must meet the system requirements. For more information, see System Requirements.
The user account that you plan to use for installation must have sufficient permissions. For more information, see Required Permissions.
Backup infrastructure components communicate with each other over specific ports. These ports must be open. For more information, see Used Ports.

Veeam Backup & Replication requires .NET Framework 4.2.5. If .NET Framework 4.2.5 is not installed, the Veeam Backup & Replication setup will install it on the backup server.
Veeam Backup & Replication requires Microsoft SQL Server deployed either locally on the backup server or remotely. If Microsoft SQL Server is not installed, the Veeam Backup & Replication setup will install Microsoft SQL Server 2012 Express Edition locally on the backup server.

If Microsoft SQL Server was installed by the previous product version, Veeam Backup & Replication will connect to the existing configuration database, upgrade it (if necessary) and use it for work.

You must remove from the target machine Veeam Backup & Replication components of versions that are not supported by the upgrade procedure. You may also need to remove earlier versions of other Veeam products and components.
