Simple setup. Two USB harddrives. One at home, one at work. The one at home is plugged in at all times doing hourly Time Machine backups. The one at work is disconnected and laying in a drawer. Encrypted with HFS. Every other week I take the home drive to work and take the work drive home to swap duties. I never have the two disks at home, one is always at work disconnected from power. This is my personal balance point between comfort, no cloud and a reliable backup. Backups are tested by restoring to a new HDD every now and then.
