Hi,
Just entered a new role in my company as junior DBA.
I am looking for assistance or guidance with regards to a script to see the weekly growth of all our databases in the company for reporting purposes.
At this stage I am looking at about +- 20 databases and we need to establish a trend for the growth in the company.
Currently I am using the following query below but would like a more detailed query so that I can get a graph going in Excel. Also this query is only for one database at a time and I would like to execute one query for all the databases.
SELECT
[database_name] AS "Database",
DATEPART(month,[backup_start_date]) AS "Month",
AVG([backup_size]/1024/1024) AS "Backup Size MB",
AVG([compressed_backup_size]/1024/1024) AS "Compressed Backup Size MB",
AVG([backup_size]/[compressed_backup_size]) AS "Compression Ratio"
FROM msdb.dbo.backupset
WHERE [database_name] = N'XXX'
AND [type] = 'D'
GROUP BY [database_name],DATEPART(mm,[backup_start_date]);
Kind Regards,

Hi,
My first step would be to set up a Central Management Server. There is a great article on it here:
http://www.brentozar.com/archive/2008/08/sql-server-2008s-new-central-management-server/
Then I would execute sp_spaceused against your group of servers, see this forum post for more..

You don't need to set up a central management server if you're the only DBA and you are only hitting one server.
You can run something like this,
CREATE TABLE #TEMP1 (
DATABASE_NAME VARCHAR(500)
, LOGICAL_NAME VARCHAR(500)
, PHYSICAL_NAME VARCHAR(500)
, FILE_SIZE INT
)
DECLARE @name VARCHAR(500)
DECLARE database_cursor CURSOR
FOR
SELECT NAME
FROM sysdatabases
ORDER BY dbid ASC
OPEN database_cursor;
FETCH NEXT
FROM database_cursor
INTO @name;
WHILE @@fetch_status = 0
BEGIN
INSERT INTO #TEMP1 (
DATABASE_NAME
, LOGICAL_NAME
, PHYSICAL_NAME
, FILE_SIZE
)
SELECT DB_NAME(database_id)
, NAME
, Physical_Name
, (size * 8) / 1024
FROM sys.master_files
WHERE DB_NAME(database_id) = @name
FETCH NEXT
FROM DATABASE_CURSOR
INTO @name;
END
CLOSE DATABASE_cursor;
DEALLOCATE DATABASE_cursor;
GO
This will return db and log file sizes, you can modify it to only show db sizes if you want and you can also look at sys.master_files to get more data like max db size, growth amount, etc. If you need more data on top of that, you can simply join to the statements I provided to get more data. You can also mix this up a bit, put the data into a permanent table for you to review in the future, etc. If you put this into a permanent table, make sure to add a datetime variable so you know when this script was run. You can also do the same thing with while loops instead of a fetch if you'd like. Also, make sure to run this against the master DB.

Kind Regards,
So take the database Name out of the WHERE clause, format the month as YYYY_MM, and maybe throw in a ROLLUP or CUBE on the GROUP BY.

instead of looping through the databases.

Here is an alternative script that could help with your trending report
DECLARE @SQLVer SQL_VARIANT
,@DBName VARCHAR(128)
,@NumDaysSMALLINT
,@SQLvarchar(1024)
,@WhereClauseVARCHAR(256)
SET @DBName = 'TFCCS_Transfers'
;
SET @NumDays = 90
;
SET @SQLVer = CONVERT(INTEGER, PARSENAME(CONVERT(VARCHAR(20),SERVERPROPERTY('ProductVersion')),4));
SET @WhereClause = 'WHERE a.type IN (''D'',''I'')
And a.backup_start_date > GETDATE()- ' + Cast(@NumDays as varchar)+''
IF @DBName IS NOT NULL
Begin
SET @WhereClause = @WhereClause + '
AND a.database_name = '''+ @DBName +''''
END
Set @SQL = '
SELECT a.database_name,a.backup_start_date,a.backup_finish_date
,datediff(minute,a.backup_start_date,a.backup_finish_date) as Duration
,b.physical_device_name AS BackupPath
,a.position
,a.type
,a.backup_size/1024/1024 AS BackupSizeMB
,' + CASE
WHEN @SQLVer < 10
THEN '0'
ELSE 'a.compressed_backup_size/1024/1024'
END + ' AS CompressedBackMB
FROM msdb.dbo.backupset a
INNER JOIN msdb.dbo.backupmediafamily b
ON a.media_set_id = b.media_set_id
' + @WhereClause + '
ORDER BY a.database_name,a.backup_start_date;'
--PRINT @SQL
Execute (@SQL);
