automating rsync

hi,
I use my macbook on a lot of nets wifi and i've to backup some my folders to a samba server.
I'd like to use a simple rsync command (I tried it from the terminal and it's ok).
Now that's the problem: I should like to run automatically a script which do these two things:

connect to the samba server (I think I could do it with the mount command like "mount -t smbfs //usr[email protected]/backups /Users/myuser/directoryToMount")
execute the rsync command (only if the mount were ok)

making the script could be easy (saving the terminal instructions in a .sh file), but how can I automatically run the script where I connect to a wifi net with a specific ssid or, better, when I connect to wired ethernet?
I also would like to view a grow popup with the result of the operation (if it's a success or a fail)

sorry for my bad English!
Alberto

You can run all those shell commands in an Automator application that can be scheduled with iCal to run at certain times.

If you are using rsync from public location jut known that the traffic is not secure.

In Automator there are actions like get servers and connect to server as well as "run shell script".

Using an RSA key pair and the scp command would enable encryption. As would using SSH to tunnel your tasks from public locations.
