I have some sql server's backup file(format .bck). In my case, I do not know log file name.
So I can't use with move in restore command.
Is there anyway to restore database without move? If yes, please guide me.
I want to use like below one.
restore database testdb from disk = 'folderpath\aatest.bak'
You sure can know the log file name and use WITH MOVE. Use RESTORE FILELISTONLY to retrieve the list of database files (including log) from the backup first.

I have a backup file of SQL Database. For Example MyDB.bak. I want to check MyDB.bak file is corrupted or not. Is there any way to check my database backup condition either corrupted or in good condition?
Note: I dont want to restore that .bak file.
Thanks
Exactly as stakx said. See the link for how to use the command:
how to use RESTORE VERIFYONLY
Check a backup file on disk
RESTORE VERIFYONLY FROM DISK = C:\AdventureWorks.BAK
GO
Check a backup file on disk for a particular backup
RESTORE VERIFYONLY FROM DISK = C:\AdventureWorks.BAK WITH FILE = 2
GO
This command will check the second backup in this backup file. To check the contents in a backup you can use RESTORE HEADERONLY and use the Position column to specify the FILE number.
I suppose that's what RESTORE VERIFYONLY is for.
"Verifies the backup but does not restore it, and checks to see that the backup set is complete and the entire backup is readable. However, RESTORE VERIFYONLY does not attempt to verify the structure of the data contained in the backup volumes. […] If the backup is valid, the SQL Server Database Engine returns a success message. "
I'm having a bit of trouble understanding the purpose of the WITH FORMAT option of the SQL Server BACKUP DATABASE command.
Using the MSDN example:
USE AdventureWorks2012;
GO
BACKUP DATABASE AdventureWorks2012
TO DISK = 'Z:\SQLServerBackups\AdventureWorks2012.Bak'
WITH FORMAT,
MEDIANAME = 'Z_SQLServerBackups',
NAME = 'Full Backup of AdventureWorks2012';
GO
I understand this deletes any existing backups and creates a new one.
If I was to omit the WITH FORMAT line, and I already had a backup at Z:\SQLServerBackups\AdventureWorks2012.Bak, what does this mean to my backup?
Is it incremental or does it overwrite with a full one?
It's a full backup, essentially appended to the file if it exists already, you'll see a File number 2 reference when you run it, and you'll see the backup file double in size. Each backup is independent of each other and either can be restored.
I can't seem to find any SQL that will clone one database in SQL Server within the same server.
Let's say I have a database called MyDB. I simply want to make a copy of MyDB to MyDb2. I thought that this would work:
BACKUP DATABASE MyDB TO MyDB2;
But I get this error when I try to execute it:
Backup device 'DbTestBack' does not exist. To view existing backup devices, use the sys.backup_devices catalog view. To create a new backup device use either sp_addumpdevice or SQL Server Management Studio.
Does anyone know what the best way to do this is? I want an exact duplicate of the original including security permissions.
A simple way is taking a back up copy of current DB and restoring it.
You Can do this in single step with a simple script
backup database MyDB
to disk='D:\MyDB.bak';
restore database MyDB2
from disk='D:\MyDB.bak'
WITH move 'MyDB_Data' to 'D:\MyDB2_Data.mdf',
move 'MyDB_log' to 'D:\MyDB2_Data.ldf';
GO
Note: I made an assumption on your current data file and log file name (MyDB_Data, MyDB_log), you need to check them and make correct
DBAtools is your friend here.
Use Copy-DbaDatabase
ie.
Copy-DbaDatabase -Source SRV1 -Destination SRV1 -Database myDB -BackupRestore -SharedPath \\<<your temporary server location such as c:\temp>>
i have the following query from msdn to restore a SQL Server database backup
RESTORE DATABASE <DBName> FROM DISK = '<BackupFilePath>\<BackupFileName>'
GO
What if you want to load the backup to a new database with new name without restoring it to replace the current one?
In the interface I would select Restore Files and Filegroups and change the to database name then it would create a new one with the backup data in it, is this possible with a simple query?
The restore command above can be used to specify a new name, but when the old database still exists on the same machine you'll get an error because it will try to use the same filenames for the data. You can use the WITH MOVE clause to get around that:
RESTORE DATABASE TestDB
FROM DISK = 'C:\Backup.BAK',
WITH MOVE 'AdventureWorks2012_Data' TO 'C:\MySQLServer\testdb.mdf',
MOVE 'AdventureWorks2012_Log' TO 'C:\MySQLServer\testdb.ldf';
GO
The above example came from the MSDN documentation on the restore command:

I have been using this query:
BACKUP DATABASE RentalEase
TO DISK = 'C:\RentalEaseBackup\RentalEase.bak'
WITH COPY_ONLY;
GO
To backup my database. Someone deleted something so now I have to restore it from a previous point in time, however I don't want to overwrite new changes (other than the deletions).
What I was thinking I could do it attached the backup to the SQL Server as a new database and then perform the necessary queries to move the few deleted rows over. However, it won't attach the RentalEase.bak file because it says it isn't a primary database file.
How can I attach the database backup so I can run the SQL queries against it?
You have to RESTORE the DB, you can't attach a backup file
RESTORE DATABASE TestDB
FROM DISK = 'c:\Northwind.bak'
WITH MOVE 'Northwind' TO 'c:\test\testdb.mdf',
MOVE 'Northwind_log' TO 'c:\test\testdb.ldf'
Full syntax here
Restore the database to a different database name, and then you can do whatever you want between the two databases (good luck!)
create a new database named RentalEase2, A restore would look like this
RESTORE DATABASE [RentalEase2] FROM DISK = N'C:\RentalEaseBackup\RentalEase.bak'
WITH FILE = 1, NOUNLOAD, STATS = 10
GO
