Fix admin backup with observer and max_execution_time?

Question

max_execution_time blocks the backup function in admin from working. So I thought I can use an observer and ini_set to increase the max_execution_time for this purpose only.

Questions is which observer would work best for this?

Or how could I find it on myself?

Answer 1

There are generic observers for controller predispatch.

like controller_action_predispatch_adminhtml_foo_bar
