SQL Express does not contain any specific scheduling tools. You can schedule T-SQL scripts to be run using Windows Task Scheduler and SQLCmd, which is a free solution as Task Scheduler is part of Windows.
For more complex needs, a third party scheduling tool is an option.

1. Yes
2. SQL Server only allows backups to local drives or LUNs. There are third party backup tools that will backup to a network drive/share. I usually have a job step that 'moves' the files to a network share after the backup is complete.
3.Yes. I assume that you are using SQLCmd.exe. Use on of the following command line arguements (switches): -U login_id [ -P password ] } OR –E trusted connection. For addtional information, see Books Online, Topic: "SQLCmd Utility'. If necessary, you can download a copy of Books Online here.
4. Since you would need two separate Jobs scheduled, one for FULL backup and one for DIFFERENTIAL, then it seems that you would not have any issue having two different names. And yes, you can dynamically create your file names.

They will not 'take' names.
You will have to dynamically, and in your script/code, create the names and provide them to the backup command.
|||I was working over the backup case but was unable to come up with a solution as to how i can automatically backup the database while dynamically allocating names to consecutive differential backups. Just a reminder, the database I am using is SQL Server 2005 Express edition.The script that is used to run the backup is
BACKUP DATABASE [DatabaseName] TO DISK = N'C:\BackUp\ST_BKUP_14_06_07'WITH DIFFERENTIAL , NOFORMAT, NOINIT, NAME = N'DatabaseName-Differential Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10
GO
I have also run the SQLCMD utility.
C:\Program Files\Microsoft SQL Server\90\Tools\Binn\SQLCMD.EXE -S [SERVER] -U backupadmin -P [PASSWORD] -i B:\ST_BACKUP\sqlscript.sql
What else must i do so that i get an automatic backup without being asked to login for every scheduled backup.Since the 'login' makes it compulsory for me to be on the system while the backup takes place. Is there any alteration i must make so that different names are alloted to consecutive backups thus not overwriting an old backup.|||
Before the part of the script that executes the BACKUP command, create a variable with the name you wish to use.
Code Snippet
DECLARE @.MyBackupName nvarchar(250)
SET @.MyBackupName = 'C:\BackUp\ST_BKUP_' + convert( varchar(10), getdate(), 112 ) + '.BAK'
BACKUP DATABASE [DatabaseName] TO DISK = @.MyBackupName
WITH DIFFERENTIAL ,
NOFORMAT,
NOINIT,
NAME = N'DatabaseName-Differential Database Backup',
SKIP,
NOREWIND,
NOUNLOAD,
STATS = 10
Every time this runs, the file name will be in the form: ST_BKUP_20070614.BAK, with the date changing every day.

Very cool.
So, for addition information I have a question:
1-Can I create a Stored Procedure with this code and then run it from a command line (cmd) ?
2-Can I to use the osql.exe to run this command or run the Stored Procedure created with this code ?
Tks,
Mura
|||1. By using OSQL or SQLCmd.
2. Yes, OSQL.exe with SQL 2000, SQLCmd.exe with SQL 2005.
You can use the Windows Scheduler service to automate this.
|||Thank you Mr. Rowland for replying.This would complete my question of how an automatic backup is done in SQL Server.

This command line prompts the user for a Server and password.
C:\Program Files\Microsoft SQL Server\90\Tools\Binn\SQLCMD.EXE -S [SERVER] -U backupadmin -P [PASSWORD] -i B:\ST_BACKUP\sqlscript.sql
I suggest that you put in the ServerName in place of [SERVER], and that you use -E instead of: -U backupadmin -P [PASSWORD]. So my suggested command line would be:
C:\Program Files\Microsoft SQL Server\90\Tools\Binn\SQLCMD.EXE -S MyServerName -E -i B:\ST_BACKUP\sqlscript.sql
|||Tkx guy,|||Thank you Mr. Rowland,You have probably selected a time format that contains characters unacceptable in a path/filename.
You may prefer to do something more like this:

hi Allan,
yes, it is possible, but not using the SQL Server Agent as SQLExpress does not provide the relative bits.. you have so to rely on the native OS scheduler, third party (or self written alternative) scheduler, or rely on the Service Broker features..
personally I usually go for the native OS scheduler, where you can define a list of xx.sql scripts to be executed by a xx.cmd file.. then the xx.cmd file, connecting to SqlCMD.exe and executing each defined xx.sql script, has to be scheduled... quiete simple and not expensive... results are output to a text file similar to:
[cmdfile.cmd]
ECHO. >>Backing up databases
SqlCmd -E -S(Local)\InstanceName -i"c:\somefolder\ScheduledBackup.sql" >c:\SomeFolder\ScheduledBackupLog.txt
ECHO. >>Sending results via mail to aministrators
SqlCmd-E -S(Local) -Q"SET NOCOUNT ON; SELECT 'Mailing log of - ' + CONVERT(varchar, GETDATE());" >E:\e-VbHot\Files\Log\MailingLogBCKschedulato.txt
SqlCmd -E -S(Local)\InstanceName -Q"SET NOCOUNT ON; DECLARE @.ret int;EXEC @.ret = [applicationDB].[dbo].[amSMTPmail] @.Server = N'smtp server name', @.Sender = N'scheduledbackup@.my_company.com', @.AddressesTO = N'admin_name@.my_company.com', @.AddressesCC = N'me@.me.com', @.AddressesCCN = NULL, @.AttachFiles = N'c:\SomeFolder\ScheduledBackupLog.txt', @.Subject = N'Backup performed', @.MessageBody = N'Backup performed', @.UserName = NULL, @.UserPassword = NULL; SELECT @.ret AS [Execution result];" >>c:\SomeFolder\MailingLog.txt
[/cmdfile.cmd]
as you can see, I do personally even send the c:\SomeFolder\ScheduledBackupLog.txt resulting file via e-mail to a "list" of addresses.. this is performed via a (free) CLR stored procedure of mine, amDBObj, where the .Net code implements a poor's man SMTP mail feature to "replace" (ok... it is not comparable with) Database Mail missing feature of SQLExpress..

|||Thanks for the info Andrea. I will look into it.

|||hi,
in addition to Jens answer, you can perhaps have a look at "third party" solutions, both commercial and free, like http://www.valesoftware.com/products-express-agent.php and http://www.codeproject.com/useritems/SQLAgent.asp to implement scheduled features..

|||Because SQL Express doesn't include the SQL Server Agent the jobs you are creating can't be executed. You'd be best served to use Windows Scheduler to run the programs performing your backups.|||I would like to schedule back up programatically in ASP. If I want to use WSH , It can only run VBScript and JScript files that are .vbs or .js. It does not run .asp files. If you wish to run the VBScript code contained in an .asp file in the WSH environment, you need to remove all of the HTML tags; the <% and %> tags, and rename the file with a ".vbs" extension. Also, remove all references to any of the ASP intrinsic objects. What would be the best solution ?|||Well, since you want to schedule automatic backups, and SQL Express doesn't support SQL Agent, I think your only option is to copy the code to a VBScript file and schedule that through Windows Scheduler. The ASP code doesn't help you with the automatic processes so it's superfluous.|||Is it possible to call vbs file from ASp Application to automate back up process?|||Hello,
A similar question. I am writing my first application. It is a small data entry and data display Form. How can the user of this deployed (if ever) application save the database to a memory stick and open it in an other instance of the same application on a different computer? It is a normal and expected when say someone writes a text, that that text can be saved, moved and opened it in any other computer -- so far the computer has a program installed which is capable to read it.
How could this be implemented? Is the application welded to a database and cann't be detached from it? Can the data itself be separated from the database as in the case of an Access or FileMaker solution?

Seemingly there are lot of newbies and not so newbies chasing after an answer for this problem.
Hello,
I need to schedule SQL Express backup from ASP Page. I was trying to use SQLDMO to schedule jobs but found that SQL Agent is not supported in Sql Express. I tried to use Scheduler.SchedulingAgent.1 to add task in schedular but getting Invalid class string error. Schedular dll is only supported in site server. What would be the best solution for me to schedule back for SQL Express?
hi,
as you already noticed, SQLExpress does not provide the native SQL Server Agent to support scheduled jobs like backups..
you have then to rely on third party scheduler, like http://www.valesoftware.com/products-express-agent.php, http://www.codeproject.com/useritems/SQLAgent.asp (free code)
personally I do recommend relying on the native OS scheduler (AT/SCHTASK) where you can define your standard schedules to execute cmd file including SQLCmd.exe calls, like
[cmd file]
SQLCmd -E -S(Local) -Q"BACKUP DATABASE [Pubs] TO DISK = N'D:\folder\Pubs.bak' WITH FORMAT, INIT, NAME = N'Pubs-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10" >>d:\folder\BckOutput.txt
[/cmd file]
which backups the Pubs database to the d:\folder\Pubs.bak file, outputting the backup execution to a text file, d:\folder\BckOutput.txt, you can later inspect for results...
additional info about this can be found at http://www.sqldbatips.com/showarticle.asp?ID=27 and http://www.sqldbatips.com/showarticle.asp?ID=29, where another free tool by an MVP fellow, Jasper Smith, is available for download to help performing backup tasks..

hi,
SQLExpress does not provide the SQL Server Agent, thus you can not schedule a "native" backup or whatever task via a SQL Server Agent job..
you have to rely on the native OS scheduler, writing your own command file including the actual BACKUP DATABASE... statement to be executed, or on other solutions even based on the OS scheduler, like http://www.sqldbatips.com/showarticle.asp?ID=27 and http://www.sqldbatips.com/showarticle.asp?ID=29, third party solutions like http://www.lazycoding.com/products.aspx or http://www.valesoftware.com/products-express-agent.php, http://www.codeproject.com/vb/net/SQLAgent.asp, or custom solutions based on the Service Broker as indicated in http://blogs.msdn.com/rogerwolterblog/archive/2006/04/13/575974.aspx

|||Excuse me, could you please tell me how can you backup your database use the Sql Express ?The complete syntax for backup is proveded in Books Online, please search there for syntax help. If you are not being allowed to login, then you are either providing the wrong instance name or you are using an account that doesn't have permissions.
The most common error people make with SQL Express is that it is installed by default to an instance name, not the default instance, so you have to pass the entire instance name when connectiong:
osql -S <machine>\SQLEXPRESS -E ...
See if adding the instance name resolves your problem.

hi,
there's not a direct equivalent.. you can resort on third pary alternatives (http://www.valesoftware.com/products-express-agent.php, never tried it), or you can go for native solutions using the OW native scheduler (AT/SCHTASKS), executing a Transact-SQL statement to perform your desired backup(s) via the SqlCMD.exe command line tool..
just create a cmd file including
[cmd file]
BACKUP DATABASE pubs TO DISK = 'c:\pubs.bak';
[/cmd file]
and schedule it via WinAT at the desired time..
voila..

|||have a look at the following post...

This is a simple scheduler system that simulates a few of the functions of the agent and might do the job that you need.

Hi i have an web app demo that allows users to add info and change attributes within a SQL 2005 Express DB. I'd like to restore a clean copy of this database every couple of hours from a .bak file using a Windows scheduled task on the server. Has anyone got a .sql script for database restoration that i could use and call using a .cmd script file? Thanks.
Hi TheGrox,
Generally speaking the sql restoration script is like this:
RESTORE DATABASE [Your_databasename] FROM DISK = N'File_Path\BCKUP.bak' WITH FILE = 1, NOUNLOAD, STATS = 10
GO
However, I don't think it can be used from a .cmd script file. To run .sql script file, you need to run it within sql server query analyzer (if you run it from a .cmd script, first it will jump up a window asking your to login to sql server, even though you enter the server name and user/password and login successfully, that sql script file will be opened there while won't be executed until you click the execute button from the GUI).
I think there are two solutions for you requirment. One solution is the easist, upgrade your sql express to a full vertion and use Server Agent-> Jobs. Run that script in a job and schedule the job to run at a sepcific time frequency. I believe it won't cost you more than 5 minutes;
The second solution is to use ado.net.Open your visual studio and create a new project, build a connection to your database first and then send the restore sqlcommand to it. Compile and build you project and after that, you create a windows schedule task and run that application regularly.
Hope my suggestion helps
|||Hi, thanks for the suggestions. The running the .sql from a .cmd file isnt a problem, i already do that to automatically back up all DB's in my SQL Express instance by having a file called BackupDB.cmd with the following code:
CLS
ECHO OFF
ECHO Testing to make sure directories exist.
IF NOT EXIST C:\SQLBackups MD C:\SQLBackups
ECHO Complete with directory creation
ECHO **********************************************************
ECHO Backing up databases......
sqlcmd -S .\SQLEXPRESS -i c:\Windows\BackupExpress.sql -o C:\SQLbackups\backup.log
ECHO **********************************************************
ECHO Backup complete. Look in the C:\SQLBackups\Backup.log file for information.
ECHO ON
The BackupExpress.sql file is simply a script that loops through all databases on the server and creates a .bak file for each of them in the specified directory. Works nicely andmeans i dont need to reconfigure anything if a new DB is created, it is just automatically included in the backups.
So i guess i just need to create a Restore.sql script using the syntax you quoted and call it as above. The command runs under the context of a valid SQL user account specified when the scheduled task is created so login is not an issue.
The script for the BackupExpress.sql file if anyone is interested in using it is:
/**File Name: BackupExpress.sqlDescription: Backs up all databases.
