I'm running a ~100Gb database on Microsoft SQL Server 2016 (SP2-GDR) Standard Edition (64-bit) on Windows Server 2016 Standard 10.0 (Build 14393: ) (Hypervisor)
Every weekday night just after 7pm I get a SQL Server Alert email like this:-
SQL Server Alert System: 'Severity 016: Miscellaneous User Error' occurred BackupVirtualDeviceFile::SendFileInfoBegin: failure on backup device
My regular daily and weekly database backups all happen at 2am (so it's not those), so I can only assume it's my hourly transaction log backups. But the only SQL agent job that fails is a C# program doing a database read (it times-out), and I can find no other errors in my SQL Agent Logs at that time. And my daily CheckDB Maintenance "Check Database Integrity Task" says the databases are fine. Any thoughts or suggestions? Thanks.
