I’m unable to create a system image backup for my Server 2008 using Windows Server Backup. When I backup my C: drive, I keep getting the error message “Volume larger than 2088958 megabytes cannot be protected” when I backup. My C: drive currently has 1.41 TB of free space and its total capacity is 2.26 TB. I’m confused. Does anyone know a fix? Any kindly advice will be appreciated.
