Backup Exec 16 seems to be available to download. But I cannot find any documents related to BE16 release? I would mostly be interested about SCL, the SCL link in Backup Exec 16 admin guide forwards to BE15 online article?
Backup Exec 16 is available to existing customers with current maintenance contracts. The software was available to support Windows Server 2016, Hyper-V 2016 and Microsoft Azure on day one of Microsoft 2016 release cycle. Backup Exec will be generally available (GA) to everyone on 7th November.
