Using SD! without TM

[Srip]

Hi,

I've read the posts about using SD! in combination with TM but I don't want to use TM.

Every night I let SD! backup my Mac, and every morning I sit down behind my computer I get a notice from TM asking to which drive it should save.
As far as I can tell SD! makes a good backup so I don't wan TM to do anything.
I've turned TM off, but it still wants to do something. How do I beat TM into submission?

Thanks!
