I created a controller function for build a backup of database or some part of it, but after created the files e sent them, the allocated memory doesn't released.

The memory use report made with rack-mini-profiler gem show that the most part of memory is occupied by ActiveReccord and it doesn't released in the end. The full report is here.

Here's what I did to reduce memory problems (Not completely resolved).

Write database intensive code in the block written as below.

ActiveRecord::Base.connection_pool.with_connection do
  write your code here...
end

Also you can try running the garbage collector with GC.start in the end of action.

Let me know if this helps
