Your script only executes to the su command. The su command spawns a new 
shell, which doesn't know nothing about the script that launched it. 
Therefor, it doesn't execute the remaining commands.

To run a script with another user priviledges, you could try:

su -c backup yourscriptname

and remove the su line from the script.
