Bamboo allows you to disable or delete Plans/Jobs that you don't want to be built:

• Disabling a Plan/Job prevents it from being built. Disabling a Plan prevents Bamboo from submitting that Plan to the build queue. Disabling a Job prevents Bamboo from building that single Job within a Plan, allowing the rest of the Plan's Jobs to be built. You can re-enable the Plan/Job, if you want to build it again.
   
  For example, if a Plan's/Job's latest build is broken and cannot be fixed quickly, you may want to disable it to temporarily stop the Plan/Job from being built.
   
• Deleting a Plan/Job removes it completely from your Bamboo system. You will need to recreate the new Plan/Job from scratch, if you want to build it again.
   
  For example, if a Plan/Job is no longer relevant, you may want to delete it.
