Thanks folks for looking into this for me -
I'm using Ola Hallengren's backup scripts and the @CopyOnly switch has not been altered from its default of 'N':
sqlcmd -E -S $(ESCAPE_SQUOTE(SRVR)) -d master -Q "EXECUTE [dbo].[DatabaseBackup] @Databases = 'USER_DATABASES', @Directory = N'\\backup_dir', @BackupType = 'FULL', @Verify = 'Y', @Compress = 'Y', @CleanupTime = 337, @CheckSum = 'Y', @LogToTable = 'Y'" -b
was definitely the last FULL backup on this database taken via that job
But speaking of intervening FULL backups...
I do see something odd with msdb..backupset -
I have a unique service account running for my SQL Server services, but NT AUTHORITY\SYSTEM is still producing backups...
My backup script job takes a FULL once per week, but some process using NT AUTHORITY\SYSTEM is taking a FULL backup every night... where is this coming from and where are those backups going???
