Description

The Export-DfrsClone cmdlet exports the Distributed File System (DFS) Replication database and volume configuration XML file settings for a given volume from the local computer, in order to clone that database on another computer. DFS Replication databases exist on every volume that contains replicated folder content and a single database contains references for all replicated folders on that volume. Once you run the cmdlet, it triggers the export in the DFS Replication service and waits for the service to complete the operation. Use Get-DfsrCloneState to monitor the export process.

DFSR does not support cloning SYSVOL or read-only replicas in Windows Server 2012 R2. These replicated folders are automatically skipped by the export process. You can only export or import one database at a time for a computer.

Follow the recommended and supported steps to perform DFS Replication database cloning, as described in Export a Clone of the DFS Replication Database in the TechNet Library. The term upstream refers to the server that is the authoritative source of both replicated file data and the DFS Replication database. The term downstream refers to the non-authoritative server that is a clone of the authoritative server.

Examples

Example 1: Export a database to a folder

PS C:\> Export-DfsrClone -Volume "C:" -Path "C:\DfsRClone" | Format-List
This operation will export the database and create a clone. It can take a long time to complete and any replication
will stop on the volume. Use Get-DfsrCloneState or DFSR event 2402 to determine when the export has succeeded. Volume: 
C:\ Path: "C:\Dfsrclone"
Are you sure you want to continue to export the database clone? 
[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"):y

CloneFolderPath : C:\Dfsrclone
CopyHint : Robocopy.exe "c:\dfsrclone" "<DestinationPath>" /B

RootFolderPath : c:\Rf01
PreseedingHint : Robocopy.exe "c:\Rf01" "<DestinationPath>" /E /B /COPYALL /R:6 /W:5 /MT:64 /XD DfsrPrivate /TEE /LOG+:preseed.log

RootFolderPath : c:\RF02
PreseedingHint Robocopy.exe "c:\RF02" "<DestinationPath>" /E /B /COPYALL /R:6 /W:5 /MT:64 /XD DfsrPrivate /TEE /LOG+:preseed.log

This command exports the DFS Replication database clone for the C: volume into the C:\DfsRClone destination folder and displays the associated replicated folders. The suggested Robocopy syntax appears in the output.

Example 2: Export a database and monitor progress

PS C:\> Export-DfsrClone -Volume "C:" -Path "C:\DfsRClone" -Force
PS C:\> Get-DfsrCloneState
PS C:\> Get-DfsrCloneState

This example demonstrates exporting the DFS Replication database clone and then uses Get-DfsrCloneState to periodically retrieve state until the replication completes.

The first command uses the Export-DfsrClone cmdlet to start the export process. You must open another Windows PowerShell console or hit CTRL+C to exit the Export-DfsrClone cmdlet. The cloning continues on the server even if the cmdlet stops running.

The second command uses the Get-DfsrCloneState cmdlet to check the state of the export process. The output appears after the command.

The third command uses the Get-DfsrCloneState cmdlet to check the state of the export process. The output indicates that the export completed successfully.

Example 3: Export and import a database

PS C:\> New-DfsReplicationGroup "RG05" | New-DfsReplicatedFolder -FolderName "RF 5" | Add-DfsrMember -ComputerName "SRV01"
PS C:\> Set-DfsrMembership -ComputerName "SRV01" -ContentPath C:\Rf05 -PrimaryMember $True -FolderName "RF05"
PS C:\> Update-DfsrConfigurationFromAD
PS C:\> New-Item -Path "C:\DfsRClone" -Type Directory
PS C:\> Export-DfsrClone -Volume C: -Path "C:\DfsRClone"
PS C:\> Robocopy.exe C:\Rf05 \\srv02\c$\Rf05 /E /B /COPYALL /R:6 /W:5 /MT:64 /XD DfsrPrivate /TEE /LOG+:preseed.log
PS C:\> Robocopy.exe C:\DfsRClone \\srv02\c$\DfsRClone /B
PS C:\> RD "C:\system volume information\dfsr" -Force -Recurse
PS C:\> Import-DfsrClone -Volume C: -Path "C:\DfsRClone"
PS C:\> Get-DfsrCloneState
PS C:\> Add-DfsrMember -GroupName "RG05" -ComputerName "SRV02" | Set-DfsrMembership -FolderName "RF05" -ContentPath "C:\Rf05"
PS C:\> Add-DfsrConnection -GroupName "RG05" -SourceComputerName "SRV01" -DestinationComputerName "SRV02"
PS C:\> Update-DfsrConfigurationFromAD

This example demonstrates the end-to-end process of cloning SRV01 and its RF05 replicated folder on C:\ to server SRV02. The first seven commands run on the upstream server, and the remaining commands run on the downstream server.

The first command, on the upstream server, uses the New-DfsReplicationGroup cmdlet to create a replication group named RG05. The output of that command is piped to the New-DfsReplicatedFolder cmdlet to create a folder named RF05, and the output of that command is piped to the Add-DfsrMember cmdlet to add the computer named SRV01 as a member.

The second command, on the upstream server, uses the Set-DfsrMembership cmdlet to modify the membership for the computer named SRV01.

The third command, on the upstream server, uses the Update-DfsrConfigurationFromAD cmdlet to update the DFS Replication configuration on the source server.

The fourth command, on the upstream server, uses the New-Item cmdlet to create a new directory in the path C:\DfsRClone.

The fifth command, on the upstream server, uses the Export-DfsrClone cmdlet to export a volume.

The sixth command, on the upstream server, uses Robocopy to copy the replicated folder directory structure to the destination server.

The seventh command, on the upstream server, uses Robocopy to copy the C:\DfsRClone directory to the destination server.

The eighth command, on the downstream server, uses RD to remove the replication directory, if it exists.

The ninth command, on the downstream server, uses the Import-DfsrClone cmdlet to import the database and volume configuration on the destination server.

The tenth command, on the downstream server, uses the Get-DfsrCloneState cmdlet to verify the completion of the import process.

The eleventh command, on the downstream server, uses the Add-DfsrMember cmdlet to add a new group on the destination server. The command pipes the output of this cmdlet to the Set-DfsrMembership cmdlet to add membership for the replicated folder group.

The twelfth command, on the downstream server, uses the Add-DfsrConnection cmdlet to add a connection for the destination server.

The final command, on the downstream server, uses the Update-DfsrConfigurationFromAD cmdlet to update the DFS Replication configuration on the destination server.
