WSUS Import-Export for disconnected network "How To"
By Diego Cabai
This are the steps for a successfully import and export of a database of WSUS that is disconnected from the network. Step 1 Import and Export: Matching Advanced Options Ensure that advanced synchronization options for express installation files and languages on the export server match the settings on the import server. To ensure that advanced synchronization options on export server match settings on import server
1. In the WSUS console of the export server, click the Options tab, and then click Advanced in the Update Files and Languages section.
2. In the Advanced Synchronization Settings dialog box, check the status of the settings for Download express installation files and Languages options.
3. In the WSUS console of the import server, click the Options tab, and then click Advanced in the Update Files and Languages section.
4. In the Advanced Synchronization Settings dialog box, make sure the settings for Download express installation files and Languages options match the selections on the export server. Important: Be sure that your WSUS content has the same drive letter on both your import/export server.
Step 2 Import and Export: Copying Updates from File System Copy updates from the file system of the export server to the file system of the import server. These procedures use the Windows Backup or Restore Wizard, but you can use any utility you like. The object is to copy updates from the file system on the export server to the files system of the import server. Important: The initial settings for access control lists differ between Windows 2000 Server and Windows Server 2003. If you are copying content from Windows 2000 Server to Windows Server 2003, you have to manually add the Network Service group to the access control list for the folder where updates are stored. Give the Network Service group Full Control. To back up updates from file system of export server to a file
1. On your export WSUS server, click Start, and then click Run.
2. In the Run dialog box, type ntbackup. The Backup or Restore Wizard starts by default, unless it is disabled. You can use this wizard or click the link to work in Advanced Mode and use the following steps.
3. Click the Backup tab, and then specify the folder where updates are stored on the export server. By default, WSUS stores updates at WSUSInstallationDrive:\WSUS\WSUSContent\.
4. In Backup media or file name, type a path and file name for the backup (.bkf) file.
5. Click Start Backup. The Backup Job Information dialog box appears.
6. Click Advanced. Under Backup Type, click Incremental.
7. From the Backup Job Information dialog box, click Start Backup to start the backup operation.
8. Move the backup file you just created to the import server.
To restore updates from a file to the file system of the import server:
1. On your import WSUS server, click Start, and then click Run.
2. In the Run dialog box, type ntbackup. The Backup or Restore Wizard starts by default, unless it is disabled. You can use this wizard or click the link to work in Advanced Mode and use the following steps.
3. Click the Restore and Manage Media tab, and select the backup file you created on the export server. If the file does not appear, right-click File, and then click Catalog File to add the location of the file.
4. In Restore files to, click Alternate location. This option preserves the folder structure of the updates: all folders and subfolders will appear in the folder you designate. You must maintain the directory structure for all folders under \WSUSContent.
5. Under Alternate location, specify the folder where updates are stored on the import server. By default, WSUS stores updates at WSUSInstallationDrive:\WSUS\WSUSContent\. Updates must appear in the folder on the import server designated to hold updates: this is typically done during installation.
6. Click Start Restore. When the Confirm Restore dialog box appears, click OK to start the restore operation. Step 3 Import and Export: Copying Metadata from Database Export update metadata from the database on the export server, and import it into the database on the import server. The WSUS Setup program copies WSUSutil.exe to the file system of the WSUS server during installation. You must be a member of the local Administrators group on the WSUS server to export or import metadata: both operations can only be run from the WSUS server itself.
Important: Never import exported data from a source that you do not trust. Importing content from a source you do not trust might compromise the security of your WSUS server. Note:
During the import or export process, the Update Service, the Windows NT service that underpins the WSUS application, is shut down.
To export metadata from the database of the export server 1. At the command prompt on the export server, navigate to the folder that contains WSUSutil.exe.
2. Type the following: wsusutil.exe export packagename logfile
For example: wsusutil.exe export export.cab export.log
That is, WSUSutil.exe followed by the export command, the name of an export .cab file, a space, and the name of a log file.
The package (.cab file) and log file name must be unique. WSUSutil.exe creates these two files as it exports metadata from the WSUS database.
3. Move the export package you just created to the import server.
To import metadata to the database of the import server
Note: It can take from 3 to 4 hours for the database to validate content that has just been imported. Please be patient. 1. At the command prompt on the import server, navigate to the directory that contains WSUSutil.exe.
2. Type the following: wsusutil.exe import packagename logfile
For example: wsusutil.exe import export.cab import.log
That is, WSUSutil.exe followed by the import command, the name of export .cab file created during the export operation, a space, and the name of a log file. WSUSutil.exe imports the metadata from the export server and creates a log file of the operation. |
