I'm having a similar problem since upgrading to Veeam One & B&R v7. When my sureBackup job runs, I get alarms for most of the Surebackup machines it creates. ButI don't know any way to suppress these alarms.
When SureBackup creates the test VMs, it seems to put them into its own VM folder that I specified when building the Virtual Lab. But I can't find anywhere in Veeam One that I can tell it to ignore alarms for a particular VM folder.
If I had the option to exclude alarms by folder, then this wouldn't be an issue.
Most of my alarms are reflecting known issues (such as low video RAM or disk space) on my production machines. I don't need to know that the problems exist on SureBackup machines.
