Using  Windows Server Backup WBADMIN on a Command Line

Using a USB drive as a destination, if I use Windows Server Backup's command line syntax as follows:
wbadmin start systemstatebackup -backupTarget:G: -quiet

Can I assume it will copy to G, but leave all existing files on G intact?  I ask because the Windows Server Backup wizard wants to completely take over a USB drive.

(This is regarding Windows Server 2008 Standard)

Thanks.

According to TECHNET:
-backupTarget
 
Specifies the storage location for this backup. Requires a hard disk drive letter (f:), a volume GUID-based path in the format of \\?\Volume{GUID}, or a Universal Naming Convention (UNC) path to a remote shared folder (\\<servername>\<sharename>\). By default, the backup will be saved at: \\<servername>\<sharename>\WindowsImageBackup\<ComputerBackedUp>\.

Important

If you save a backup to a remote shared folder, that backup will be overwritten if you use the same folder to back up the same computer again. In addition, if the backup operation fails, you may end up with no backup because the older backup will be overwritten, but the newer backup will not be usable. You can avoid this by creating subfolders in the remote shared folder to organize your backups. If you do this, the subfolders will need twice the space as the parent folder.

So in direct answer to your question, yes, it will leave the files intact.
