AlphaVSS - Montando em uma pasta RRS feed

  • Pergunta

  • Olá a todos!

    Estou desenvolvendo uma aplicação para backup e estou testando o AlphaVSS.

    Usei como exemplo o trecho do código abaixo que está nesse site:

    Nesse exemplo ele adiciona o volume gerado a uma unidade.
    Eu gostaria que esse volume não ficasse disponível como uma unidade e sim montado em uma pasta ou até mesmo oculto.

    Existe essa possibilidade?

    // Getting information on the files to copy (This is not part of the VSS action)
    String _Source1 = @"C:\_ISUG_VSS_DB\20140106_ISUG_VSS_DB.mdf";
    String _Source2 = @"C:\_ISUG_VSS_DB\20140106_ISUG_VSS_DB_log.ldf";
    String _Destination = @"V:\QQ";
    FileInfo MyFileInfo = new FileInfo(_Source1);
    String _Volume = MyFileInfo.Directory.Root.Name;
    // VSS step 1: Initialize
    IVssImplementation _vssImplementation = VssUtils.LoadImplementation();
    IVssBackupComponents _backup = _vssImplementation.CreateVssBackupComponents();
    // VSS step 2: Getting Metadata from all the VSS writers
    // VSS step 3: VSS Configuration
    _backup.SetContext(VssVolumeSnapshotAttributes.Persistent | VssVolumeSnapshotAttributes.NoAutoRelease);
    _backup.SetBackupState(false, true, Alphaleonis.Win32.Vss.VssBackupType.Full, false);
    // VSS step 4: Declaring the Volumes that we need to use in this beckup.
    // The Snapshot is a volume element (Here come the name "Volume Shadow-Copy")
    // For each file that we nee to copy we have to make sure that the propere volume is in the "Snapshot Set"
    Guid MyGuid01 = _backup.StartSnapshotSet();
    Guid MyGuid02 = _backup.AddToSnapshotSet(_Volume, Guid.Empty);
    // VSS step 5: Preparation (Writers & Provaiders need to start preparation)
    // VSS step 6: Create a Snapshot For each volume in the "Snapshot Set"
    /* At this point we have a snapshot!
    /* This action should not take more then 60 second, regardless of file or disk size.
    /* THe snapshot is not a backup or any copy!
    /* please more information at
    // VSS step 7: Expose Snapshot
    /* Snapshot path look like:
     * \\?\Volume{011682bf-23d7-11e2-93e7-806e6f6e6963}\
     * The build in method System.IO.File.Copy do not work with path like this,
     * Therefor, we are going to Expose the Snapshot to our application,
     * by mapping the Snapshot to new virtual volume
     * - Make sure that you are using a volume that is not already exist
     * - This is only for learning purposes. usually we will use the snapshot directly as i show in the next example in the blog
    _backup.ExposeSnapshot(MyGuid02, null, VssVolumeSnapshotAttributes.ExposedLocally, "L:");
    // VSS step 8: Copy Files!
    /* Now we start to copy the files/folders/disk!
    /* Execution time can depend on what we are copying
    /* We can copy one element or several element.
    /* As long as we are working under the same snapshot,
    /* the element should be in consist state from the same point-in-time
    String sVSSFile1 = _Source1.Replace(_Volume, @"L:\");
    String sVSSFile2 = _Source2.Replace(_Volume, @"L:\");
    if (File.Exists(sVSSFile1))
        System.IO.File.Copy(sVSSFile1, _Destination + @"\" + System.IO.Path.GetFileName(_Source1), true);
    if (File.Exists(sVSSFile2))
        System.IO.File.Copy(sVSSFile2, _Destination + @"\" + System.IO.Path.GetFileName(_Source2), true);
    // VSS step 9: Delete the snapshot (using the Exposed Snapshot name)
    foreach (VssSnapshotProperties prop in _backup.QuerySnapshots())
        if (prop.ExposedName == @"L:\")
            Console.WriteLine("prop.ExposedNam Found!");
            _backup.DeleteSnapshot(prop.SnapshotId, true);
    _backup = null;
    Console.WriteLine("END OK. Click any Key to close the application");
