I have a SQL backup job created by a maintenance plan that began failing after a power outage resulting in exception logs and dump files. The databases are in 'Simple' recovery model and the backups are 'Full' backups. The DBCC CHECKDB WITH NO_INFOMSGS, ALL_ERRORMSGS command returned no errors. I discovered after stopping/starting the SQL database engine service that the backups complete successfully once or twice, but then begin failing again due to same reason. So, I am having to stop/start the SQL service each day to get the backups to complete.Using this version: [code="plain"]Microsoft SQL Server 2014 - 12.0.2000.8 (X64) Feb 20 2014 20:04:26 Copyright (c) Microsoft Corporation Standard Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1) (Hypervisor)[/code]Failure reason from Error Log:[code="plain"]Failed: (-1073548784) Executing the query "BACKUP DATABASE [Color] TO DISK = N'\\\\BackupFolder..." failed with the following error: "BACKUP DATABASE is terminating abnormally.".
