What is a simple command line program or script to backup SQL server databases?

Question
I've been too lax with performing DB backups on our internal servers.
Is there a simple command line program that I can use to backup certain databases in SQL Server 2005? Or is there a simple VBScript?
Solution
To backup a single database from the command line, use osql or sqlcmd.
"C:\Program Files\Microsoft SQL Server\90\Tools\Binn\osql.exe"
-E -Q "BACKUP DATABASE mydatabase TO DISK='C:\tmp\db.bak' WITH FORMAT"
You'll also want to read the documentation on BACKUP and RESTORE and general procedures.
OTHER TIPS
I use ExpressMaint.
To backup all user databases I do for example:
C:\>ExpressMaint.exe -S (local)\sqlexpress -D ALL_USER -T DB -BU HOURS -BV 1 -B c:\backupdir\ -DS
Schedule the following to backup all Databases:
Use Master
Declare @ToExecute VarChar(8000)
Select @ToExecute = Coalesce(@ToExecute + 'Backup Database ' + [Name] + ' To Disk = ''D:\Backups\Databases\' + [Name] + '.bak'' With Format;' + char(13),'')
From
Master..Sysdatabases
Where
[Name] Not In ('tempdb')
and databasepropertyex ([Name],'Status') = 'online'
Execute(@ToExecute)
There are also more details on my blog: how to Automate SQL Server Express Backups.
I found this on a Microsoft Support page http://support.microsoft.com/kb/2019698.
It works great! And since it came from Microsoft, I feel like it's pretty legit.
Basically there are two steps.
- Create a stored procedure in your master db. See msft link or if it's broken try here: http://pastebin.com/svRLkqnq
Schedule the backup from your task scheduler. You might want to put into a .bat or .cmd file first and then schedule that file.
sqlcmd -S YOUR_SERVER_NAME\SQLEXPRESS -E -Q "EXEC sp_BackupDatabases @backupLocation='C:\SQL_Backup\', @backupType='F'" 1>c:\SQL_Backup\backup.log
Obviously replace YOUR_SERVER_NAME with your computer name or optionally try .\SQLEXPRESS and make sure the backup folder exists. In this case it's trying to put it into c:\SQL_Backup
You can use the backup application by ApexSQL. Although it’s a GUI application, it has all its features supported in CLI. It is possible to either perform one-time backup operations, or to create a job that would back up specified databases on the regular basis. You can check the switch rules and exampled in the articles:
I'm using tsql on a Linux/UNIX infrastructure to access MSSQL databases. Here's a simple shell script to dump a table to a file:
#!/usr/bin/ksh
#
#.....
(
tsql -S {database} -U {user} -P {password} <<EOF
select * from {table}
go
quit
EOF
) >{output_file.dump}
Eventual if you don't have a trusted connection as the –E switch declares
Use following command line
"[program dir]\[sql server version]\Tools\Binn\osql.exe" -Q "BACKUP DATABASE mydatabase TO DISK='C:\tmp\db.bak'" -S [server] –U [login id] -P [password]
Where
[program dir] is the directory where the osql.exe exists
On 32bit OS c:\Program Files\Microsoft SQL Server\
On 64bit OS c:\Program Files (x86)\Microsoft SQL Server\
[sql server version] your sql server version 110 or 100 or 90 or 80 begin with the largest number
[server] your servername or server ip
[login id] your ms-sql server user login name
[password] the required login password
Below is the simple script to make database backup.
DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
-- specify database backup directory
SET @path = 'C:\Backup\'
-- specify filename format
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name NOT IN ('master','model','msdb','tempdb') -- exclude these databases
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
BACKUP DATABASE @name TO DISK = @fileName
FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor
You could use a VB Script I wrote exactly for this purpose: https://github.com/ezrarieben/mssql-backup-vbs/
Schedule a task in the "Task Scheduler" to execute the script as you like and it'll backup the entire DB to a BAK file and save it wherever you specify.
SET NOCOUNT ON;
declare @PATH VARCHAR(200)='D:\MyBackupFolder\'
-- path where you want to take backups
IF OBJECT_ID('TEMPDB..#back') IS NOT NULL
DROP TABLE #back
CREATE TABLE #back
(
RN INT IDENTITY (1,1),
DatabaseName NVARCHAR(200)
)
INSERT INTO #back
SELECT 'MyDatabase1'
UNION SELECT 'MyDatabase2'
UNION SELECT 'MyDatabase3'
UNION SELECT 'MyDatabase4'
-- your databases List
DECLARE @COUNT INT =0 , @RN INT =1, @SCRIPT NVARCHAR(MAX)='', @DBNAME VARCHAR(200)
PRINT '---------------------FULL BACKUP SCRIPT-------------------------'+CHAR(10)
SET @COUNT = (SELECT COUNT(*) FROM #back)
PRINT 'USE MASTER'+CHAR(10)
WHILE(@COUNT > = @RN)
BEGIN
SET @DBNAME =(SELECT DatabaseName FROM #back WHERE RN=@RN)
SET @SCRIPT ='BACKUP DATABASE ' +'['+@DBNAME+']'+CHAR(10)+'TO DISK =N'''+@PATH+@DBNAME+ N'_Backup_'
+ REPLACE ( REPLACE ( REPLACE ( REPLACE ( CAST ( CAST ( GETDATE () AS DATETIME2 ) AS VARCHAR ( 100 )), '-' , '_' ), ' ' , '_' ), '.' , '_' ), ':' , '' )+'.bak'''+CHAR(10)+'WITH COMPRESSION, STATS = 10'+CHAR(10)+'GO'+CHAR(10)
PRINT @SCRIPT
SET @RN=@RN+1
END
PRINT '---------------------DIFF BACKUP SCRIPT-------------------------'+CHAR(10)
SET @COUNT =0 SET @RN =1 SET @SCRIPT ='' SET @DBNAME =''
SET @COUNT = (SELECT COUNT(*) FROM #back)
PRINT 'USE MASTER'+CHAR(10)
WHILE(@COUNT > = @RN)
BEGIN
SET @DBNAME =(SELECT DatabaseName FROM #back WHERE RN=@RN)
SET @SCRIPT ='BACKUP DATABASE ' +'['+@DBNAME+']'+CHAR(10)+'TO DISK =N'''+@PATH+@DBNAME+ N'_Backup_'
+ REPLACE ( REPLACE ( REPLACE ( REPLACE ( CAST ( CAST ( GETDATE () AS DATETIME2 ) AS VARCHAR ( 100 )), '-' , '_' ), ' ' , '_' ), '.' , '_' ), ':' , '' )+'.diff'''+CHAR(10)+'WITH DIFFERENTIAL, COMPRESSION, STATS = 10'+CHAR(10)+'GO'+CHAR(10)
PRINT @SCRIPT
SET @RN=@RN+1
END
If you can find the DB files... "cp DBFiles backup/"
Almost for sure not advisable in most cases, but it's simple as all getup.
