Basically, I recommend you to stop properly the Veeam services before upgrading (services.msc). When the backup is done, you can close Veeam software and restart the Windows server (reboot). If the Veeam Backup Server is deployed on a Virtual Machine, execute a backup of this VM with Veeam B&R or a snapshot. The first step is to realize a configuration backup of Veeam server (“Configuration Backup” menu on the screenshot below) and SQL database backup. If you need to upgrade your Veeam Backup Server (to v11) you can follow this article. This technical article provides a step by step guide to upgrade Veeam B&R 11 to Veeam B&R 12 (Veeam Backup and Replication 12 Upgrade). You can learn more about Veeam Backup and Replication v12 new features here. Veeam will do a bunch of live demos to show off new v12 capabilities. Don’t miss the launch event, you can register here. This build is fully supported by Veeam technical support, who is standing by to assist all early adopters. Veeam enables organizations to confidently move to the cloud, avoiding lock-in with cloud mobility, and simplifying operations for Backup Administrators (jobs management, backup migration, etc.). With this release, Veeam wants to allow you to control and securely backup and recover your data anywhere in the hybrid cloud. Next week, Veeam will release Veeam Backup and Replication 12, which contains some significant improvements.
