Question on query to show DB names, status, recover model & backup size.

  • I'm an Oracle DBA that used to work with MSSQL a few years ago, and now find myself taking over admin duties for a large number of MSSQL databases, from version 2008 & up. 

    I am putting together a report for management showing all the databases and their current status, from which I will make recommendations on how best to proceed with backup strategies etc.

    From searches I have found / cobbled together a query to show me database size, status, recovery mode and last backup for all the databases on a given server, but I would like to add backup size as well so I can prioritize by size to see which, if any I will possibly implement incremental backups for. 

    This is the query I am running:


    SELECT sdb.Name AS DatabaseName,
    COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_finish_date), 101),'-') AS LastBackUpTime, sdb.recovery_model_desc, sdb.state_desc
    FROM sys.databases sdb
    LEFT OUTER JOIN msdb.dbo.backupset bus ON bus.database_name = sdb.name
    where sdb.name not in ('master','model','msdb','tempdb')
    GROUP BY sdb.Name, sdb.recovery_model_desc, sdb.state_desc

    I'd like to add backup size to this query, but am not familiar enough with MSSQL data dictionary to easily find out how, (oracle is my main DBA expertise) so hoping someone here can point me in right direction.

    I'm not even sure if I'm using the best system view(s) to accomplish what I want here.

    This query gives me too many rows, and if I use a MAX function it still doesn't look right :


    SELECT sdb.Name AS DatabaseName,
    COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_finish_date), 101),'-') AS LastBackUpTime, sdb.recovery_model_desc, sdb.state_desc,bus.backup_size AS BackupSize
    FROM sys.databases sdb
    LEFT OUTER JOIN msdb.dbo.backupset bus ON bus.database_name = sdb.name
    where sdb.name not in ('master','model','msdb','tempdb')
    GROUP BY sdb.Name, sdb.recovery_model_desc, sdb.state_desc, bus.backup_size

    Getting database size would probably also suffice now that I think about it, since it will also give me what I am looking for, but last backup size would be nice. 

    Thanks in advance..

    I used your query and you can add more into your query but you may want to start using a CTE to get some of this. It sounds like you are looking for something along the lines of :
    WITH Backups (DatabaseName, LastBackUpTime, recovery_model, state_desc, BackupSize, DatabaseSize, rn)
    AS
    (
    SELECT sdb.Name AS DatabaseName,
    COALESCE(CONVERT(VARCHAR(12), bus.backup_finish_date, 101),'-') AS LastBackUpTime,
    sdb.recovery_model_desc,
    sdb.state_desc,
    bus.backup_size/1024/1024 AS BackupSize,
    CAST(SUM(mf.size) * 8. / 1024 AS DECIMAL(8,2)) as DatabaseSize,
    row_number() over(partition by sdb.name order by backup_finish_date desc) as rn
    FROM sys.databases sdb
    LEFT OUTER JOIN msdb.dbo.backupset bus
    ON bus.database_name = sdb.name
    INNER JOIN sys.master_files mf
    on sdb.database_id = mf.database_id
    where sdb.name not in ('master','model','msdb','tempdb')
    Group by sdb.Name, bus.backup_finish_date, recovery_model_desc, bus.backup_size, sdb.state_desc
    )

    SELECT
        DatabaseName,
        LastBackupTime,
        recovery_model,
        state_desc,
        BackupSize,
        DatabaseSize
    FROM Backups
    WHERE rn = 1

    Some other things to consider -
    You may also want to include backup type or filter it to just full backups. As it is now, it would include any backup.
    Hopefully no one is backing up to NUL but those would be included as well. Not sure what you would want to do with copy only backups.
    I get what you are trying to do and think I understand why...in your position, I would also worry about any databases in full recovery that don't have log backups. Or sizes of the logs just because the log backups aren't frequent enough. There are probably other things but thought I'd mention those.

  • Thanks - I'd played with my original query and seemed to get what I wanted, thought I'd tried this last week and it didn't work: 


    SELECT sdb.Name AS DatabaseName,
    COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_finish_date), 101),'-') AS LastBackUpTime, sdb.recovery_model_desc, sdb.state_desc,max(bus.backup_size)/1024/1024/1024 AS BackupSize
    FROM sys.databases sdb
    LEFT OUTER JOIN msdb.dbo.backupset bus ON bus.database_name = sdb.name
    where sdb.name not in ('master','model','msdb','tempdb')
    GROUP BY sdb.Name, sdb.recovery_model_desc, sdb.state_desc

    Yours looks better, but on 10.50.4302 returns no rows. Seems to work fine on the newer sql servers however.

    Yes I'll be checking log backups too, I've been bitten by this before being used to Oracle automatically archiving its logs.

    The change in this one from the original one you posted is that you are querying for the max backup size (in addition to the max last backup time). So it returns the max size of any of the backups for that database. I returning the size for the last backup. So they return different things.

    Thanks - trying to figure out why your query does not return any rows in version 10.50.x but works ok on 10.0.4x and it has me stumped so far..

    No idea other than if it had no user databases as those are excluded.

  • No, when I run my original query it returns 37 rows, when I also run this query to get database sizes it returns no rows: 

    SELECT  sys.databases.name,
        CONVERT(VARCHAR,SUM(size)*8/1024)+' MB' AS [Total disk space]
    FROM   sys.databases 
    JOIN   sys.master_files
    ON    sys.databases.database_id=sys.master_files.database_id
    GROUP BY  sys.databases.name
    ORDER BY  sys.databases.name

    Seems that server has different permissions set up on how I connect using windows authentication, and appears to have SA acct disabled, so perhaps something to do with that?

    If you get some with your original ones and none with the one I wrote and there are user databases then it's more likely due to permissions for the system views/tables.
    Check the permssions on all three of the views/tables between the different instances. And make sure to check the public role as well. The difference would likely be the permissions on sys.master_files.
