Restauration SQL Server entièrement automatisée

Question

Je ne maîtrise pas très bien les commandes SQL Server.

J'ai besoin d'un script pour restaurer une base de données à partir d'un fichier .bak et déplacer les fichiers logic_data et logic_log vers un chemin spécifique.

Je peux faire:

restore filelistonly from disk='D:\backups\my_backup.bak'

Cela me donnera un jeu de résultats avec une colonne LogicalName, ensuite je dois utiliser les noms logiques du jeu de résultats dans la commande de restauration:

restore database my_db_name from disk='d:\backups\my_backups.bak' with file=1,
move 'logical_data_file' to 'd:\data\mydb.mdf',
move 'logical_log_file' to 'd:\data\mylog.ldf'

Comment capturer les noms logiques du premier jeu de résultats dans des variables qui peuvent être fournies à la commande "move"?

Je pense que la solution pourrait être triviale, mais je suis assez nouveau sur SQL Server.

Voici le processus de stockage T-SQL de restauration entièrement automatisé. Accepte trois (3) paramètres.

1. Base de données cible
2. Base de données source
3. Emplacement complet du nom du fichier de sauvegarde
   (\\yourserver\yourshare\backupfile.bak ou simplement c:\backup.bak)

Answer 2

RESTORE FILELISTONLY produit un jeu de résultats documenté dans MSDN . Vous devez ensuite itérer cet ensemble de résultats et créer un RESTORE ... MOVE approprié ... La façon dont vous capturez et itérez l'ensemble de résultats dépend de votre environnement. Dans une application C #, vous utiliseriez un SqlDataReader. En T-SQL pur, vous utiliseriez INSERT ... EXEC .

Le squelette d'une solution SQL pure serait:

declare @filelist table (LogicalName nvarchar(128), PhysicalName nvarchar(260), Type char(1), FilegroupName varchar(10), size int, MaxSize bigint, field int, createlsn bit, droplsn bit, uniqueid uniqueidentifier, readonlylsn bit, readwritelsn bit, backupsizeinbytes bigint, sourceblocksize int, filegroupid int, loggroupguid uniqueidentifier, differentialbaselsn bit, differentialbaseguid uniqueidentifier, isreadonly bit, ispresent bit, tdethumbprint varchar(5));
insert into @filelist exec sp_executesql N'restore filelistonly from disk=''D:\backups\my_backup.bak''';

set @sql = N'RESTORE database my_database from disk ''D:\backups\my_backup.bak'' with ';
select @sql = @sql + N' move ' + LogicalName + N' to ' udf_localFilePath(PhysicalName) + N','
from @filelist;

set @sql = substring(@sql, 1, len(@sql)-1); -- remove last ','
exec sp_executesql @sql;

Ce n'est pas du code de travail réel, mais juste pour vous donner l'idée. Vous pouvez également utiliser un curseur au lieu de la construction non standard d'affectation à l'intérieur de la requête de @sql

Sachez que la liste des colonnes du jeu de résultats RESTORE FILELISTONLY diffère entre les versions de SQL Server. Reportez-vous aux spécifications de la version cible pour la liste correcte.

J'ai eu le même problème, mais dans mon environnement, j'ai de nombreux fichiers de sauvegarde (sauvegardes plus rapides) et j'ai dû restaurer à un emplacement personnalisé.

Answer 7

cela pourrait aider. Je voulais créer un script pour un client avec les variables minimales requises pour être définies pour plusieurs sauvegardes de base de données restaurées à partir d'un seul emplacement. J'ai essayé d'éviter d'utiliser du SQL dynamique car je pense que tout devient un peu compliqué.

Answer 8

Encore une autre modification/implémentations. Voici mes 2 cents. J'ai modifié le script de Mevdiven ci-dessus, afin qu'il restaure le fichier dans le répertoire de données de la base de données actuelle. J'ai un problème en ce que je ne veux pas utiliser l'emplacement défini dans le fichier de sauvegarde.

J'attrape le répertoire de données utilisé par le premier fichier maître

SELECT top(1) @v_strRestorePath =  physical_name FROM sys.master_files

Et utilisez-le comme chemin de données de destination.

J'ai également constaté que la table ## FILE_LIST traînait, alors je la laisse tomber vers la fin.

Les extra - ' sont juste pour que le SQL soit joli sur débordement de pile

J'ai créé une nouvelle version basée sur les réponses trouvées ici. Il devrait fonctionner avec les dernières versions de SQL Server.

Fourni avec un emplacement de sauvegarde, il restaure la base de données à partir de la sauvegarde et déplace les fichiers MDF et LDF vers un emplacement spécifié.

declare @databaseName nvarchar(max);
declare @backUpDiskLocation nvarchar(max);
declare @physicalMDFLocation nvarchar(max);
declare @physicalLDFLocation nvarchar(max);

set @databaseName = '[<DB_Name>]';
set @backUpDiskLocation = 'C:\SQL-BACKUP\<backUP-Name>.bak';
set @physicalMDFLocation = 'C:\SQL\SQLData\<MDF-Name>.mdf';
set @physicalLDFLocation = 'C:\SQL\SQL-LOG\<LDF-Name_log>.LDF'

if (DB_ID(@databaseName)) is not null
Begin
DECLARE @kill varchar(8000); SET @kill = ''; 
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';' 
FROM master..sysprocesses 
WHERE dbid = DB_ID(@databaseName)
EXEC(@kill);
 DECLARE @Alter nvarchar(max); SET @Alter = 'ALTER DATABASE ' + @databaseName +' SET offline  WITH Rollback Immediate'
 EXEC (@Alter)
END

declare @sql nvarchar(max)
set @sql = N'restore filelistonly from disk=''' + @backUpDiskLocation +'''';

select @sql
create table #filelist (LogicalName nvarchar(128), PhysicalName nvarchar(260), Type char(1), FilegroupName varchar(10), size bigint, MaxSize bigint, field int, createlsn bit, droplsn bit, uniqueid uniqueidentifier, readonlylsn bit, readwritelsn bit, backupsizeinbytes bigint, sourceblocksize int, filegroupid int, loggroupguid uniqueidentifier, differentialbaselsn bit, differentialbaseguid uniqueidentifier, isreadonly bit, ispresent bit, tdethumbprint varchar(5), SnapshotUrl nvarchar(128));
insert into #filelist exec sp_executesql @sql;
ALTER TABLE #filelist add id int identity(1,1)
update #filelist set PhysicalName = @physicalMDFLocation where [id]= 1
update #filelist set PhysicalName = @physicalLDFLocation where [id]= 2
select * from #filelist

set @sql = N'RESTORE database '+ @databaseName +' from disk = '''+ @backUpDiskLocation +''' with replace, ';
select @sql
select @sql = @sql + N' move ''' + LogicalName + N''' to ''' + PhysicalName + N''',' from #filelist;

set @sql = substring(@sql, 1, len(@sql)-1); -- remove last ','

select @sql
exec sp_executesql @sql;

drop table #filelist

Answer 10

je ne sais pas comment ajouter des commentaires sous une solution particulière mais je viens de mettre en œuvre la solution fournie par Mevdiven ci-dessus ...

Il y a un léger problème avec la table de dépôt dans mon environnement (Server 08 r2). J'ai dû modifier cela pour utiliser l'ID d'objet afin de réussir la chute.

J'ai également eu des problèmes en raison d'un grand nombre de partitions dans le fichier de sauvegarde, j'ai donc dû changer la chaîne pour qu'elle soit nvarchar (MAX).

J'ai également ajouté la possibilité de restaurer la base de données dans un autre répertoire (car nos environnements dev vs prod ont des chemins différents)
