Use Auto Backup Charging just like a normal flash drive. Once the card capacity is filled, it will remind you to replace the card. Don't worry replacing the old card to a new, it does not duplicate the backup, instead, Qubii remembers where it left off and start to back up data from there. No internet or wifi needed. Less wait and more efficient.
