Problem fixing TWRP backup


hi friends,
I rooted my Moto X today . Titanium Backup froze Motorola OTA, because I want 4.4.4
I got it installed busy box and now I am trying to backup with TWRP but I get this error like " Unable to create folder:/data/media/0/twrp and "failed to made backup folder ".
What can I do to fix TWRP backups and debug other issues? I`ve done something wrong ? It`s because of the busy box ?


Same error appeared to me. Backing up via OTG it`s the best you can do. I am now backing this way with the most recent version and it works. :)
