Question about Wbadmin syntax

I currently use the old Windows Backup (2007), which works well, but is not very flexible for scheduling and other features.

The old app produces 2 files, one under the "name" of the computer, presumably containing full incremental backups of all files on C:\. The other is named "WindowsImageBackup", containing a system image.

I'd like to migrate to using Wbadmin scripts for backups and my question is how to configure the "Wbadmin start backup" command with the necessary paramenters so both a full backup and a system image is produced. Can this, for example, be accomplished in one wbadmin line or not? If not, will it work with two lines (one for each type of backup) in sequence?

All guidance greatly appreciated.
