How to Deploy Veeam Configuration Database in SQL AlwaysOn Availability Group

Configuration Notes

• It is best practice to keep the Veeam Backup & Replication application and its configuration database on the same server to maintain the lowest latency and highest performance.^[1] 
• The included SQL Express instance is considered adequate for protecting up to 500 machines.^[2]
• The best way to protect the Veeam Backup & Replication configuration database is to use the built-in Configuration Backup.
• Hosting the Veeam Backup & Replication configuration database on a remote SQL Instance may negatively impact the performance of the Veeam Backup & Replication software. The Veeam Backup & Replication configuration database is highly transactional, and network congestion could delay communication with the configuration database.
• Please be advised that SQL AlwaysOn Availability Groups require the databases to be in Full Recovery mode. Veeam Backup and Replication does not currently truncate its database, as we expect it to be in simple recovery mode. This will require you to manually truncate the SQL log file to ensure it doesn't grow too large.
  

4. If the Veeam Server is not on the domain, on the SQL Server Instance page of the install wizard, specify the SQL Authentication account details.
5. Proceed with the installation of the Veeam software.
6. After the installation has been completed, connect to SQL AOAG and add the Veeam configuration database to the Availability Databases.
