Sql-server – SQL Server 2012 database backup successfully report but no backup file

backupmaintenancesql serversql-server-2012

enter image description here

I have created maintenance plan in SQL Server 2012. And every day, the maintenance plan should backup the database. There is no database backup file when I look in the folder where the backups must be stored. But SQL Server logs history about this maintenance plan are successful.

What is the problem?

I am using SQL Server 2012. The operating system is Windows Server 2008 R2.

Thank you for paying attention.

The msdb database keeps history of where, when, who, how big etc. of backups. I have often needed to know where a backup went or who did it or when was the last backup.

This is set to return the last two days of backup history. You can put a specific database in the value, if you leave it blank it will return for all databases. This query works for 2005+. Just tested in 2012.

/*
Find Where DB Backups Went Physical Location
For last two days.  
backupset.type  
D --> FULL
I --> DIff or incrimental 
L --> Log backups
*/

DECLARE @dbname     sysname
SET @dbname = ''

SELECT  
     @@servername [ServerName]
    ,master.sys.sysdatabases.name [DatabaseName]
    ,msdb.dbo.backupset.backup_start_date [Backup Date]
    ,msdb.dbo.backupset.user_name
    ,datediff(second, msdb.dbo.backupset.backup_start_date,
    msdb.dbo.backupset.backup_finish_date) [Duration-seconds]
    ,msdb.dbo.backupmediafamily.physical_device_name [File Location]    
    ,msdb.dbo.backupset.type
FROM
    msdb.dbo.backupmediafamily,
    master.sys.sysdatabases
    LEFT OUTER JOIN
    msdb.dbo.backupset 
    ON master.sys.sysdatabases.name = msdb.dbo.backupset.database_name  
WHERE 
    msdb.dbo.backupset.type in( 'D', 'I', 'L')
AND msdb.dbo.backupmediafamily.media_set_id = msdb.dbo.backupset.media_set_id
and msdb.dbo.backupset.backup_start_date > getdate() - 2
AND master.sys.sysdatabases.name not in ('pubs','northwind', 'tempdb','adventureworks')
AND master.sys.sysdatabases.name like '%' + @dbname + '%'
ORDER BY    
    master.sys.sysdatabases.name

Sql-server – Scheduled backup task doesn’t always backup all databases despite always saying job successful

I would add TRY/CATCH blocks to handle errors and log them. The DB could be in single user, being restored or whatever.

Without this, errors can abort in a way that no errors are logged (statement, batch, scope, connection etc)

With TRY/CATCH then everything except for compile or connection aborting errors are logged? but I doubt this is the case.

I'd also use sys.databases which replaces sysdatabases and read more flags:

-- declares etc

BEGIN TRY

    DECLARE db_cursor CURSOR FOR  
    SELECT name, state, user_access
    FROM sys.databases 
    WHERE name NOT IN ('tempdb')

    OPEN db_cursor   
    FETCH NEXT FROM db_cursor INTO @name, @state, @user_access

    WHILE @@FETCH_STATUS = 0   
    BEGIN   

        SET @fileName = @path + @name + '.bak'
        IF @state = 0 AND user_access = 0
        BEGIN
            BEGIN TRY
                BACKUP DATABASE @name TO DISK = @fileName  WITH INIT
            END TRY
            BEGIN CATCH
                -- log but do not rethrow so loop continues
            END CATCH
            WAITFOR DELAY '00:00:20'
        END
        ELSE
           --log user and/or state issues

        FETCH NEXT FROM db_cursor INTO @name 
    END   

    CLOSE db_cursor   
    DEALLOCATE db_cursor

END TRY
BEGIN CATCH
  -- some useful stuff here
END CATCH

Sql-server – Backup database and clean old backup question

You should probably move from maintenance plans to SQL Agent Jobs and leverage a script like those written by http://ola.hallengren.com/. You would create a Job Step for each database. It will give you the flexibility that you are looking for.

UPDATE: My info above was incorrect. You can use the Ola.Hallengren.com script to do what you are looking for without having to add a job step for each database. After reviewing the script info I saw this:

CleanupTime

Specify the time, in hours, after which the backup files are deleted. If no time is specified, then no backup files are deleted.

Backup files are deleted after each database is backed up and verified. Backup files are deleted only if the backup and verification of the database were successful.

DatabaseBackup has a check to verify that transaction log backups that are newer than the most recent full or differential backup are not deleted. This is to guarantee that you can always perform a point-in-time restore.
