Please reconnect Qubii to the iPhone lightning cable, restart your iPhone, then do a full backup again. You may need to use iPhone lightning cable that is different from the one you are using.
If solution 1 doesn't work, please try solution 2.
*It may take longer for the initial full backup. Please DO NOT disconnect the power cord while Qubii is backing up. If you need to stop the back up, tap the "STOP" button on the Qubii app to safely disconnect it from the device.
STEP 1: Reformat your microSD card.
STEP 2: Delete all back up records from the Qubii app.
STEP 3: Restart your iPhone and try backing up again from the beginning.
Reformatting the microSD card will verify that there is no data on the card that could have caused the error.
