Dapatkan cadangan lengkap terakhir dan cadangan log transaksi untuk setiap basis data

Cara menulis skrip atau kueri yang akan menampilkan cadangan lengkap terakhir dan cadangan log terakhir untuk setiap database di setiap server produksi menggunakan tabel sistem "backupset" dan tabel cadangan terkait.

Sesuatu seperti ini akan memberi Anda hasil yang Anda cari. Kueri di bawah ini menarik cadangan terbaru dari jenis penuh, diferensial, atau cadangan log untuk setiap database.

;with backup_cte as
(
    select
        database_name,
        backup_type =
            case type
                when 'D' then 'database'
                when 'L' then 'log'
                when 'I' then 'differential'
                else 'other'
            end,
        backup_finish_date,
        rownum = 
            row_number() over
            (
                partition by database_name, type 
                order by backup_finish_date desc
            )
    from msdb.dbo.backupset
)
select
    database_name,
    backup_type,
    backup_finish_date
from backup_cte
where rownum = 1
order by database_name;

Saya menulis posting tentang menggunakan backupset di sini jika Anda tertarik lebih detail tentang tabel. Sederhananya di sini adalah permintaan untuk menarik apa yang Anda inginkan.

use msdb
go

-- D = Full, I = Differential and L = Log.
-- There are other types of backups too but those are the primary ones.
SELECT backupset.database_name, 
    MAX(CASE WHEN backupset.type = 'D' THEN backupset.backup_finish_date ELSE NULL END) AS LastFullBackup,
    MAX(CASE WHEN backupset.type = 'I' THEN backupset.backup_finish_date ELSE NULL END) AS LastDifferential,
    MAX(CASE WHEN backupset.type = 'L' THEN backupset.backup_finish_date ELSE NULL END) AS LastLog
FROM backupset
GROUP BY backupset.database_name
ORDER BY backupset.database_name DESC

Catatan: Disebutkan bahwa saya telah bergabung dengan backmediaset dan itu tidak diperlukan. Ini benar dan saya hanya bisa berasumsi bahwa saya lupa menghapusnya dari permintaan asli di tautan. Saya sudah menghapusnya dari sini.

Anda mungkin ingin melihat msdbdatabase, untuk detailnya.

Contohnya:

DECLARE @DBName SYSNAME;
SET @DBName = DB_NAME(); -- modify these as you desire.
SET @DBName = NULL; -- comment this line if you want to limit the displayed history

SELECT DatabaseName = bs.database_name
    , BackupStartDate = bs.backup_start_date
    , CompressedBackupSize = bs.compressed_backup_size
    , ExpirationDate = bs.expiration_date
    , BackupSetName = bs.name
    , RecoveryModel = bs.recovery_model
    , ServerName = bs.server_name
    , BackupType = CASE bs.type 
        WHEN 'D' THEN 'Database' 
        WHEN 'L' THEN 'Log' 
        ELSE '[unknown]' END
    , LogicalDeviceName = bmf.logical_device_name
    , PhysicalDeviceName = bmf.physical_device_name
FROM msdb.dbo.backupset bs
    INNER JOIN msdb.dbo.backupmediafamily bmf 
        ON [bs].[media_set_id] = [bmf].[media_set_id]
WHERE (bs.database_name = @DBName
    OR @DBName IS NULL)
    AND bs.type = 'D'
ORDER BY bs.backup_start_date DESC;

untuk menampilkan backup penuh terakhir, Diff, Log untuk setiap basis data dengan mempertimbangkan menunjukkan nol jika tidak ada cadangan yang pernah diambil . menggunakan pivot (dimodifikasi dari sumber )

perhatikan bahwa tanpa bergabung ke master.sys.databases dan hanya mengandalkan msdb.dbo.backupset Anda tidak akan menemukan dbs yang tidak memiliki cadangan

  SELECT  name ,
            recovery_model_desc ,
            state_desc ,
            d AS 'Last Full Backup' ,
            i AS 'Last Differential Backup' ,
            l AS 'Last log Backup'
    FROM    ( SELECT    db.name ,
                        db.state_desc ,
                        db.recovery_model_desc ,
                        type ,
                        backup_finish_date
              FROM      master.sys.databases db
                        LEFT OUTER JOIN msdb.dbo.backupset a ON a.database_name = db.name
            ) AS Sourcetable 
        PIVOT 
            ( MAX(backup_finish_date) FOR type IN ( D, I, L ) ) AS MostRecentBackup

‌ Berdasarkan permintaan @SQLBoy kita dapat menulis kueri di bawah ini untuk menyertakan BackupSize dan BackupSet.Name dalam kueri ini. Saya menghilangkan data yang diputar dan membuatnya lebih sederhana

WITH    backupsetSummary
          AS ( SELECT   bs.database_name ,
                        bs.type bstype ,
                        MAX(backup_finish_date) MAXbackup_finish_date
               FROM     msdb.dbo.backupset bs
               GROUP BY bs.database_name ,
                        bs.type
             ),
        MainBigSet
          AS ( SELECT   db.name ,
                        db.state_desc ,
                        db.recovery_model_desc ,
                        bs.type ,
                        bs.name AS BackupSetName ,
                        bs.backup_size ,
                        bs.backup_finish_date
               FROM     master.sys.databases db
                        LEFT OUTER JOIN backupsetSummary bss ON bss.database_name = db.name
                        LEFT OUTER JOIN msdb.dbo.backupset bs ON bs.database_name = db.name
                                                              AND bss.bstype = bs.type
                                                              AND bss.MAXbackup_finish_date = bs.backup_finish_date
             )
    SELECT  *
    FROM    MainBigSet

Anda dapat menggunakan skrip berikut:

1) jika Anda ingin mendapatkan cadangan terbaru hanya gunakan perintah berikut:

SELECT sdb.Name AS DatabaseName,
COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_finish_date), 101),'-') AS LastBackUpTime
FROM sys.sysdatabases sdb
LEFT OUTER JOIN msdb.dbo.backupset bus ON bus.database_name = sdb.name
GROUP BY sdb.Name

2) jika Anda ingin mendapatkan riwayat cadangan untuk semua database dalam tujuh hari terakhir:

SELECT 
   CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server,
   msdb.dbo.backupset.database_name, 
   msdb.dbo.backupset.backup_start_date, 
   msdb.dbo.backupset.backup_finish_date,
   msdb.dbo.backupset.expiration_date,
   CASE msdb..backupset.type 
       WHEN 'D' THEN 'Database' 
       WHEN 'L' THEN 'Log' 
   END AS backup_type, 
   msdb.dbo.backupset.backup_size, 
   msdb.dbo.backupmediafamily.logical_device_name, 
   msdb.dbo.backupmediafamily.physical_device_name,  
   msdb.dbo.backupset.name AS backupset_name,
   msdb.dbo.backupset.description
FROM   msdb.dbo.backupmediafamily 
   INNER JOIN msdb.dbo.backupset ON msdb.dbo.backupmediafamily.media_set_id = msdb.dbo.backupset.media_set_id 
WHERE  (CONVERT(datetime, msdb.dbo.backupset.backup_start_date, 102) >= GETDATE() - 7) 
ORDER BY 
   msdb.dbo.backupset.database_name,
   msdb.dbo.backupset.backup_finish_date

referensi: http://www.mssqltips.com/sqlservertip/1601/script-to-retrieve-sql-server-database-backup-history-and-no-backups/

Tanggal cadangan terakhir untuk semua database. Sederhana.

SELECT sdb.Name AS DatabaseName,
COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_finish_date), 101),'-') AS LastBackUpTime
FROM sys.sysdatabases sdb
LEFT OUTER JOIN msdb.dbo.backupset bus ON bus.database_name = sdb.name
GROUP BY sdb.Name

Saya pikir di bawah ini adalah permintaan yang kita semua cari:
