You can use the tools that are included with Microsoft Office SharePoint Server 2007 to back up and restore Web applications. The Central Administration Web site offers a simple, UI-based method to manage content backup and recovery and also to view job history and status. The Stsadm command line tool offers a faster and more flexible command line-based approach to content backup and recovery. You can use the Stsadm command-line tool together with Windows Scheduler to schedule delayed or periodic backups.

For more information about how the data protection tools that are included with Office SharePoint Server 2007 compare with other tools for protecting the SharePoint data, see Choose backup and recovery tools (Office SharePoint Server).

You can back up and restore data for Office SharePoint Server 2007 by using any of the following methods.

Back up Web applications by using SharePoint built-in tools

Use this procedure to back up a Web application by using the SharePoint Central Administration Web site.

Important :
Membership in the Farm Administrators SharePoint group is the minimum that you must have to complete this procedure.

To back up a Web application by using the user interface

On the SharePoint Central Administration Web site, on the Operations page, in the Backup and Restore section, click Perform a backup.
On the Select Component to Backup page, select the check boxes for the Web applications that you want to back up. The check boxes for any subordinate Web applications and content databases are automatically selected. Click Continue to Backup Options.
On the Select Backup Options page, a differential backup backs up data that is created or changed since the last backup. If you are performing a combination of full and differential backups, the recovery process requires that you have the last full backup and the last differential backup.
- In the Backup Content section, verify that the Web applications that you selected is displayed.
- In the Type of Backup section, select Full.
- In the Backup File Location section, type the UNC pat the backup folder.
Click OK.

You can view the backup job status on the back up status page by clicking Refresh. The page also refreshes every 30 seconds automatically. Backup and recovery is a Timer service job, which may take few seconds for the backup to start.

If you receive any errors, you can find more information by looking in the spbackup.log at the UNC path you specified earlier.

Use this procedure to back up a Web application by using the Stsadm command-line tool.

Important :
Membership in the Administrators group on the local computer is the minimum required to complete this procedure.

To back up a Web application by using the command line

On the drive on which SharePoint Products and Technologies is installed, change to the following directory: %COMMONPROGRAMFILES%\Microsoft shared\Web server extensions\12\Bin.
If you do not already know what node you want to back up, type the following command:

stsadm –o backup –showtree

Remarque :

Items enclosed by square brackets ([ ]) cannot be directly selected for backup but are backed up when their parent item is selected.
To back up a Web application, type the following command:

stsadm -o backup -directory <\\server name\folder name> -backupmethod full -item <Web application name>

where \\server name\folder name is the UNC path of the backup folder and where Web application name is the name of the Web application that you want to back up. You might use the full farm path notation as displayed by the showtree parameter or the name of the component in the path if it has a unique name — for example, Windows SharePoint Services Web Application\SharePoint-80.

Remarque :
Items enclosed by square brackets ([ ]) cannot be directly selected for backup but are backed up when their parent item is selected.

If the backup is completed successfully, the Command Prompt window displays the following text:

Completed with 0 warnings.
Completed with 0 errors.
Backup completed successfully.
---------------------------------------------------------
Operation completed successfully.

If there are errors or warnings, or if the backup is not completed successfully, review the spbackup.log file in the folder that you specified in step 3.

Schedule or delay backups

You cannot schedule backups from the SharePoint Central Administration Web site. However, you can automate the process by creating a batch file and then by using Task Scheduler in Windows Server 2003 to run the batch file at a specific time. Because performance can be affected when doing backups with the Office SharePoint Server 2007 built-in tools, you might want to schedule your backups for off-peak times such as at night or on weekends.

Use this procedure to create a batch file that will run a full backup of the Web application. This procedure assumes that you have already created a shared folder for your backups. For more information about how to create a shared folder, see Préparer la sauvegarde et la restauration d’une batterie de serveurs (Office SharePoint Server 2007).

Conseil :
When you use Task Scheduler, make sure that the system date and time on your computer are accurate. To verify or change this information, double-click the time indicator on the taskbar.

To create a batch file

Click Start, and then click Run.
Type notepad, and then click OK.
In Notepad, type the following text:
```
@echo off
echo ===============================================================
echo Back up sites for the farm to C:\backup
echo ===============================================================
cd \Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN
@echo off
stsadm -o backup -directory <\\server name\folder name> -backupmethod full -item <Web application name> 
echo completed
```
where \\server name\folder name is the UNC path of the backup folder and where Web application name is the name of the Web application that you want to back up. You might use the full farm path notation as displayed by the showtree parameter or the name of the component in the path if it has a unique name — for example, Windows SharePoint Services Web Application\SharePoint-80.
In Notepad, on the File menu, click Save As.
In the Save As box, select the folder where you want to keep your batch file.
Use the ".bat" file name extension; type the name of the file in the File name box, for example, backup_batch.bat.
In the Save as type box, click All files.
Click Save.

To schedule a backup

Start the Scheduled Task Wizard, and then click Next.
Click Browse, locate the batch file that you created, and then click Open.
Type a name for your task, for example, backup_batch.
Select how frequently you want this task to be performed (for example, weekly), and then click Next.
To automatically perform this backup periodically, select an interval such as Weekly or Monthly. To perform this backup one time, or to delay a single backup, select One time only.
Determine a time and start date for your backup.
Type a name and password for a user, and then click Next. This task will run as if it were started by that user.
Click Finish.

To configure advanced settings for the task, select the Open advanced properties for this task when I click Finish check box in the final page of the wizard. This opens the properties dialog box for the task when you click Finish. You can then change the program being run on the Task tab, fine-tune the schedule on the Schedule tab, customize settings on the Settings tab, or set user and group permissions on the Security tab.
