Usage: WBADMIN START BACKUP     [-backupTarget:{TargetVolume | TargetNetworkShare}]     [-include:VolumesToInclude]     [-allCritical]     [-noVerify]     [-user:UserName]     [-password:Password]     [-noInheritAcl]     [-vssFull]     [-quiet]  Runs a one-time backup using the specified parameters. When no options are  specified and a scheduled backup is enabled, runs a backup using the settings for the scheduled backup. If parameters are specified, it runs a Volume Shadow Copy Service (VSS) copy backup and will not update the history of the files  that are being backed up.  -backupTarget   Storage location for this backup. Requires drive letter or                  Universal Naming Convention (UNC) path to a remote shared                  network folder (\\servername\sharename\).                  NOTE: If a remote shared folder is specified, this backup will                 overwrite any existing backups of this server in that location.  -include        Comma-delimited list of volume drive letters, volume mount                  Points, or GUID-based volume names to include in the backup.                  Should be used only when -backupTarget is specified.  -allCritical    Automatically includes all critical volumes (volumes that                  contain operating system components) in the backup. Can be                  used with the -include parameter. Useful if you are creating                  a backup for full system or system state recovery.                  Should be used only when -backupTarget is specified.  -noVerify       If specified, backups written to removable media (such as a                  DVD) are not be verified for errors. If you do not use this                  parameter, backups written to removable media are verified.  -user           Specifies the user name with write access to the remote shared                 folder, if the backup destination is a remote shared folder.  -password       Password for the user name that is specified by the parameter                  -user.  -noInheritAcl   If specified, the credentials specified are applied to                  \\\WindowsImageBackup\                  folder that contains the backup. To access the backup later,                  you must use these credentials or be a member of the                  Administrators or Backup Operators group on the computer with                 the shared folder. If -noInheritAcl is not used, the access                 control list (ACL) permissions from the shared folder are                  applied to the  folder by default so that anyone                  with access to the remote shared folder can access the backup.  -vssFull        If specified, performs a full backup using Volume Shadow Copy                  Service (VSS). Each file's history will be updated to reflect                  that it was backed up. If this parameter is not specified,                  START BACKUP makes a copy backup, but the history of files                  being backed up is not updated.                 CAUTION: Do not use this parameter if you are using a product                  other than Windows Server Backup to back up applications that                  are on the volumes included in the current backup. Doing so can                 potentially break the incremental, differential, or other type                 of backups the other backup product is taking.  -quiet          Runs the command with no prompts to the user.  Example: WBADMIN START BACKUP -backupTarget:f: -include:e:,d:\mountpoint,\\?\Volume{cc566d14-44a0-11d9-9d93-806e6f6e6963}\
