So I installed TWRP and my Moto G4 is rooted. All working fine. I did a couple of backups and everything seemed to work fine. Then I tried to update my backups and get this " Failed to create ....../backup/.... (I/O Error) Failed to make backup folder" In recovery I can see the 2 previous, in file explorer I an also see the folder. Any ideas how to fix this. I want to do a full wipe and restore, but with no recent backup I reluctant to do this.
