Using DpmBackup with Mount Points

Published : September 27, 2005

When you run DpmBackup and you are protecting volumes that do not have drive letters assigned to them (volume mount points), the backup shadow copies created by DpmBackup are mounted in the DPM namespace, using only the volume globally unique identifier (GUID). To identify the mapping between the volume GUID in the protected path on the DPM server and the actual protected volume on the protected file server, use the DpmMetadata.xml document that is produced when you run DpmBackup successfully.

DpmMetadata.xml is saved in the \Program Files\Microsoft Data Protection Manager\DPM\Backup Documents\ folder. DpmMetadata.xml provides an XML representation of the DPM topology, as shown in the following example.

Example

Volume mount point on protected file server FS01 (volume GUID: 7fa3a5e6-929c-11d9-a3b7-000c76289bfb)

C:\mountpoints\volume6

Path created by DpmBackup

C:\Program Files\Microsoft Data Protection Manager\DPM\Volumes\Shadowcopy\FS01\7fa3a5e6-929c-11d9-a3b7-000c76289bfb\Replicadir

Protected path on DPM server

C:\Program Files\Microsoft Data Protection Manager\DPM\Volumes\Replica\FS01\7fa3a5e6-929c-11d9-a3b7-000c76289bfb\Replicadir

Representation in DpmMetadata.xml

<Component Name="Replica\Mount point C:\mountpoints\volume6 on server FS01">

<RestoreData ProtectionGroup="Sales" FileServer="FS01" 

FileServerVolumeGUID="\\?\Volume{7fa3a5e6-929c-11d9-a3b7-000c76289bfb}\" 

FileServerBasePath="C:\mountpoints\volume6\"

DpmServerBasePath="C:\Program Files\Microsoft Data Protection Manager\DPM\Volumes\Replica\FS01\

7fa3a5e6-929c-11d9-a3b7-000c76289bfb\ReplicaDir\" /> 

</Component>
