Hi All Friend,
I also have error 20 with iBackupBot. After that i know about error. Please reinstall and backup with itune. After that use iBackupbot to find My Angela file. Don't replace all of hack Document and Library . Please Check and replace in your device files to replace hack of Document and Library files. I'm also IOS 9.3.4 and working now.
Thanks.....
