Ottieni l'ultimo backup completo e il backup del registro delle transazioni per ciascun database

Come scrivere uno script o una query che visualizzerà l'ultimo backup completo e l'ultimo backup del registro per ciascun database su ciascuno dei server di produzione utilizzando la tabella di sistema "set di backup" e le relative tabelle di backup.

Qualcosa del genere dovrebbe darti l'output che stai cercando. La query seguente estrae il backup più recente di tipo completo, differenziale o backup del registro per ciascun 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;

Ho scritto un post sull'uso di backupset qui se sei interessato a maggiori dettagli sulla tabella. Semplicemente però ecco una domanda per estrarre ciò che vuoi.

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

Nota: è stato menzionato che mi ero unito a backmediaset e non era necessario. Questo è vero e posso solo supporre che ho dimenticato di rimuoverlo dalla query originale nel collegamento. L'ho rimosso da qui.

Probabilmente vuoi guardare il msdbdatabase, per quei dettagli.

Per esempio:

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;

per mostrare gli ultimi backup completi, Diff, Log per ciascun database, considerando la possibilità di mostrare null se non viene mai eseguito alcun backup . usando pivot (modificato dalla fonte )

notare che senza unirsi ai database master.sys e fare affidamento solo su msdb.dbo.backupset non si troveranno i dbs che non hanno backup

  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

‌Sulla base della richiesta @SQLBoy possiamo scrivere la query seguente per includere BackupSize e BackupSet.Name in questa query. Ho omesso i dati pivot e li ho resi più semplici

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

puoi usare il seguente script:

1) se si desidera ottenere l'ultimo backup, utilizzare solo il comando seguente:

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

riferimento: http://blog.sqlauthority.com/2010/11/04/sql-server-finding-last-backup-time-for-all-database/

2) se si desidera ottenere la cronologia dei backup per tutti i database negli ultimi sette giorni:

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

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

Ultima data di backup per tutti i database. Semplice.

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

Penso che di seguito sia la query per la quale tutti abbiamo cercato:
