how to automount a drive before backup starts

[kerasmus]

... I have a SMB drive "backup" that I want to backup to. This drive will only be mounted when backup is going on, and then unmount it after backup is done. I have applescripts to do the mount/umount of the drive. And SuperDuper! has the feature to run scripts before and after a copy starts. ...

I am in the same boat, except that I don't have any prepared scripts, and I don't know much of anything about scripting. I can learn what I need to, but I was hoping someone could point me toward information that will help me create this simple script to mount a network drive (via Ethernet) before smart backup (to a disk image) and unmount it afterwords.
