I want to set up Acronis True Image 2017 to do a complete backup of my C drive on alternate days. I want to guard against ramsomware by having a complete backup to restore my system. I want to connect one of the external hard drives each day, leaving the other drive disconnected, so as to avoid having it encrypted by ransomware. I can designate one drive as G and the other as H. There is no option in Acronis to allow a backup on alternate days, just a daily or weekly schedule. I have set up 2 backup schedules, one with G as the destination and a second with H destination. They are set to run at different times of the day. If only one of the drives is connected, what happens when the computer tries to run a backup to the disconnected drive?
