Summarize this article:

Choose "add features" and install Windows Server Backup if it is not already installed. Type "wbadmin start systemstatebackup." This will back up the whole volume. Scheduled backups must be backed up to a local physical dedicated drive.
Open Server Manager. Click start, run and command to get to a command line. Add the parameter "-allcritical" to back up all critical volumes instead of just system state data. Use the command line tool to create scheduled backups.
