Im Currently using AWS RDS on my system, and my storage is too big. And then i house keeping them and delete about 200 TB. But in my billing the storage didnt decrease at all. How can i decrease my storage on AWS RDS ?

You can't decrease storage as you provision upfront. The only way to decrease storage is dump your database to disk on another (EC2?) server and create a new RDS instance with less diskspace.

  • What i mean is before i house keeping, my billing charge for RDS storage is $7k and after house keeping my billing is the same as before ($7k) – Fahmil Furqon Nov 13 '17 at 09:48
  • That's my point, your bill will never go down unless you remove instances or make your current instances smaller, which you can't. That why you have to reload and start a new (smaller) instance. – Exelian Nov 13 '17 at 11:35
  • @Fahmil. You are billed for allocated disk space, not used disk space. – John Hanley Nov 13 '17 at 17:49
