Restore a whole volume to e.g. a mounted USB Disk

Oct 9, 2009 at 2:01 PM


guess I have a ShadowCopy of my C: Drive.
How would I restore this whole volume to my mounted USB Disk (e.g. H: Drive)?

Is there a way to do this with AlphaVSS?

I haven't personally worked with the restore features of VSS, but the functionality should be there. All I can do is to refer you to the MSDN documentation on VSS, or leave someone else with more experience in this area to answer your question.

Thx for the reply. Now I know that there should be a way to do this.
I'll try to find the way and when succeeded I'll leave a comment here.

But anyway, further help would be definitely usefull :).

If you have a snapshot created, you are able to read directly from the SnapshotDeviceObject (you get this from a VssSnapshotProperties Instance) with the AlphaFS Library.
e.g. with Alphaleonis.Win32.Filesystem.Directory.GetDirectories(SnapshotDeviceObject + @"\") you will get the directories of the root of the snapshot.

Hi Ephraim,

I am new to vss. I am able to do a volume snap, but when trying to restore, I get that vss is in an inconsistent state and the event viewer:
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface.  hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process. 
sure i am running as admin.

here is the code:
            vss = Alphaleonis.Win32.Vss.VssUtils.LoadImplementation();  // load the correct version of alphavss
            bk = vss.CreateVssBackupComponents();  // Alphaleonis.Win32.Vss.IVssBackupComponents
            bk.InitializeForRestore( strdoc );   // strDoc is from IVssBackupComponents::SaveAsXml
            Alphaleonis.Win32.Vss.VssSnapshotProperties prop = bk.GetSnapshotProperties( a_gidSnapshotId );
            bk.RevertToSnapshot( prop.SnapshotId, true );

do you have an example that is able to restore?
