# Before You Begin

Before you install Veeam App for Palo Alto Networks XSIAM, do the following for each Veeam Backup & Replication and Veeam ONE instance you plan to use with the app:

- For Veeam Backup & Replication, make sure that you add your syslog server to the Veeam Backup & Replication console. For more information, see [Specifying Syslog Servers](https://helpcenter.veeam.com/docs/vbr/userguide/syslog_servers.html) in the Veeam Backup & Replication User Guide.
- For Veeam ONE, make sure that you configure your syslog server in the Veeam ONE server settings. For more information, see [Syslog Integration](https://helpcenter.veeam.com/docs/one/userguide/syslog_settings.html) in the Veeam ONE User Guide.
