You can use a keystroke recorder, such as CE Software's QuicKeys, to issue
the necessary keystrokes to ADSM.  In fact, you could create a sequence
that would be run on startup and would launch ADSM, issue the incremental
command, wait for it to be completed, and then quit ADSM.  I have also
seen on the internet a program that will allow you to perform tasks upon
Shutdown, so you could possible to the backup then.

Basically, you just need to issue a Command-I to ADSM.  Be sure to set up
the domain (volumes you want backed up) in the prefernces file.

Hope this helps,
