Hello, I want to backup my entire C drive to the external backup drive, but I can't find a solution on how to do that. I cannot just copy the entire C drive to the External Disk, because of TrustedInstaller. I also can't use any cloning software, because it erases everything from the external drive. I have other important files there, so I do not want it to be formatted. I just want to add more backup files from the C drive to the External Drive, without the need of searching for them on my entire C drive manually. Is there any way to get my entire C Drive to the Backup Drive, without erasing the existing files on the Backup Drive?
