Hi, we are trying to use the RCT . Few questions related to it:
the query WMI GetVirtualDiskChanges or VHD QueryChangesVirtualDisk returns access_denied error while getting the disk changes for full. Any idea on what is best to perform full backup ?
We tried the below procedure and found to get the corrupted disk.
Create production snapshot using WMI
then we manually copied the base read-only vhdx file to some other directory (say c:\temp\vm1)
Created reference point (say, RCT_id1).
Created snapshot again
Run in GetVirtualDiskChanges query to get changed blocks since RCT_id1
Read the blocks (offset/length) - (seek and read) to get the data to buffer.
Write the buffer to c:\temp\vm1\ (saved in step 2) - overwrite
Open/attach the c:\temp\vm1\vm1.vhdx =====> This is corrupted.
Any help here is appreciated
