REPLICATING LIBRARY CONTENT BETWEEN MULTIPLE LIBRARY
SERVERS
SCVMM has no capability to replicate the content of the library servers. If your
organization has 20 SCVMM library servers, you have 20 file shares, all with their
own content that you need to keep maintained. If you add a VHD to one library,
you need to manually add it to the other 19 file shares.
Numerous solutions can keep the content replicated, but all involve initially
having a single master library—to which you add new content, and from which
you update/remove existing content. You then use a technology to synchronize
this master copy to all of the other library servers. One way to replicate the
content is to use the Microsoft Robust File Copy tool (Robocopy), which copies
the content from the master to all of the other libraries in the organization. Once
the copy is complete, a manual refresh of the library is performed in SCVMM to
load the new content, which can be performed in PowerShell by using the Read-
SCLibraryShare cmdlet. Another option is to use Distributed File System
Replication (DFSR). This allows master-slave relationships to be created and
automatically replicates changes from the master to the slave library shares, but
the new content won’t show until a library refresh is performed. You cannot use
Distributed File System Namespaces (DFSN) as a location for libraries, only the
DFSR replication component.
If you have other replication technologies in your organization, that is fine. The
