Your Backup file is empty, see the Compressed file size is (36.8KB), read the Chip again.

Which Programmer do you use? Do you use a Clip, solder wires or de-solder the Chip?

open the backup with a hex editor and scroll through the file.You don`t need to know what all the code means, just look ,it will mostly be all FF`s . That means its empty. 32MB of FF`s will compress down to a small file size. If your backup was good and had more code it would compress down to over 5MB
