Recover from VHD File - VM - Hyper-V

Hi,

Here is the scenario:

VM had driver issues
restored back to older version via previous snapshot
VM working and put required content back into server

After doing the above, we realised that there was a folder that we needed, now that the restore has happened via snapshot we cannot retrieve these files.

I have noticed that when I open the VHD file there is a folder called [DELETED] I was getting really happy thinking the files were in here but it was not the case. The file was opened using 7zip. This folder is not visable when attaching it.

I have another file with the extension .AVHD which is currently in use (which I believe is the differential file that looks at the parent VHD file). When I try to open the file via 7zip there is another file within called the .mbr file. I cannot seem to open this file and view its contents.

Do you guys suggest what can be done to retrieve the content that would have been within: C:\Program Files (x86)\

Any help will be appreciated.

Regards

When you reverted the Snapshot, you "went back in time" and hence all files that have been created since the snapshot was created "have been lost".

Those missing files and folders are located in the AVHD file.

It's possible you could get them back by merging the AVHD with the current parent disk but all changes would be lost in the current VM.

I would recommend making an entire copy of the current VM, with it's AVHD, and Merging this content with parent, and then open the VM, and recover the files you require.

You will not be able to extract the files from within the AVHD files.

So to get an understanding here, even though I didn't take a snapshot of the current state, I reverted back in time as you call it. You are now saying those files are still there?

I have copied the parent and AVHD file onto my desktop. Will I be able merge these two files and retrieve those lost files? If so, how will I be able merge the files together.

Thanks in advance for the help on this.

You will need to use Hyper-V to complete the merge.

I have just merged the files and there is no sign of the old files. I can see the new files on the parent file now.

So that means the files are lost then?
