Pertumbuhan Ukuran Database SQL Server menggunakan riwayat Cadangan

Hai,

Manajer dan pelanggan sering menanyakan berapa pertumbuhan ukuran database.

Grafik pertumbuhan ukuran database sangat penting untuk tatanan penyimpanan baru. Karena perusahaan Enterprise ingin membeli penyimpanan baru dalam satu atau dua tahun tidak setiap 2-3 bulan.

Anda dapat menganalisis pertumbuhan ukuran database menggunakan riwayat pencadangan dengan skrip berikut.

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;
