Feature request: Add option to clean temporary file in /tmp/ folder as soon as it is copied to backup location

Feature request: Add option to clean 1GB temporary file in /tmp/ folder as soon as it is copied to backup location.
I have limited space of 1.5GB in tmp directory.
Please add option so that when the app gets a 1GB block from client then it copies that block from /tmp/ directory to backup location then delete that block from /tmp/ before requesting next 1GB block from client

Thanks
