Having a scheduling problem

[RobLewis]

I'm trying to schedule a backup. I want SD! to
--run a script to mount the destination volume and disable Time Machine
--do a Smart Backup
--run another script to re-enable Time Machine
--unmount the destination volume.

There seems to be just one problem: When SD! starts up, it notices that the destination volume isn't mounted (because the first script hasn't run yet) and gets hung up.

I can think of a few possible solutions, but it seems like the most straightforward would be a new option to mount the volume before doing anything else.

Can you suggest a short-term solution and maybe consider this for a future version? It might be cool to have a command-line version of SD! so it could be called from a shell script, sort of like I'm doing with Disk Utility:
>diskutil mount MyBackupVol
