You can change the status of any backup from In Progress to Failed using the command
omnidbutil -clear
Be careful of this, you don't want to run thsi if there are valid backups running, it is a All or Nothing command, that s, will change every running backup from InProgress to Failed, whether iit is a valid backup of not
I'm not quite sure what the 'ndm' process you referred to, however, since the 'd' is right next to 's', I think that you were referring to 'bsm'
