Hi,
Managers and customers are asking frequently what is the database size growth.
Database size growth grafic is very important for the new storage order. Because Enterprise companies want to purchase new storage in one or two years not every 2-3 month.
You can analyse the database size growth using backup history with following script.
DECLARE @startDate datetime;
SET @startDate = GetDate();
SELECT PVT.DatabaseName
, PVT.[0], PVT.[-1], PVT.[-2], PVT.[-3], PVT.[-4], PVT.[-5], PVT.[-6]
, PVT.[-7], PVT.[-8], PVT.[-9], PVT.[-10], PVT.[-11], PVT.[-12]
FROM
(SELECT BS.database_name AS DatabaseName
,DATEDIFF(mm, @startDate, BS.backup_start_date) AS MonthsAgo
,CONVERT(numeric(10, 1), AVG(BF.file_size / 1048576.0)) AS AvgSizeMB
FROM msdb.dbo.backupset as BS
INNER JOIN
msdb.dbo.backupfile AS BF
ON BS.backup_set_id = BF.backup_set_id
WHERE NOT BS.database_name IN
('master', 'msdb', 'model', 'tempdb')
AND BF.[file_type] = 'D'
AND BS.backup_start_date BETWEEN DATEADD(yy, -1, @startDate) AND @startDate
GROUP BY BS.database_name
,DATEDIFF(mm, @startDate, BS.backup_start_date)
) AS BCKSTAT
PIVOT (SUM(BCKSTAT.AvgSizeMB)
FOR BCKSTAT.MonthsAgo IN ([0], [-1], [-2], [-3], [-4], [-5], [-6], [-7], [-8], [-9], [-10], [-11], [-12])
) AS PVT
ORDER BY PVT.DatabaseName;
