Folder replication internals RRS feed

  • Question


  • On the following Microsoft Forum page:
    Setup: How to replace system drive and how Windows Home Server handles the primary hard drive.
    http://social.microsoft.com/Forums/en-US/whsfaq/thread/cdb387f1-9baa-4ae3-a74b-ff351dc1c0bf

    Is states:

    "The primary data partition (the second partition on the primary disk) is special because that is where Drive Extender starts working it's magic from. This is where all "tombstones" are stored. Tombstones are really NTFS reparse points that DE understands. They are tiny files that redirect to one or two "shadows".  The shadows are where your data really is, and shadows always exist on partitions other than the primary."

    Now clearly something is incorrect here.  In a one drive system the primary partition is the only place the data really could be, and on a two drive system where folder duplication is used one copy of all that data would also have to be on the primary partition of the first drive.  Can you clarify/correct this FAQ?

  • You are right, this 2007 FAQ is not completely correct. Correct info can be found on Windows Home Server support pages, technical brief Drive Extender.

    Basically the primary disk can contain both tombstones and shadows, all other disks contain only shadows. In each case the shadows are stored in hidden folder "DE"  in the root of the partition.
