This issue occurs if the password of the account that is used to back up the virtual machine or the virtual machine directory name has an ampersand (&).
Note: This issue is not restricted to ampersand and may also occur if there are other special character in the password or the virtual directory name.
To resolve this issue:
  • Ensure that the password does not contain special characters. For example, the non-standard US-English ASCII characters.
  • Ensure that the virtual machine directory does not have any special characters.
