Hi bob3160, I've never used goback so I can't comment.
I have BootBack ISR which is the same as first defense(both use leapfrog's snapshot technology).This app allows you to make a snapshot of your whole OS,up to 10 snapshots providing there is enough unused space to do so,that you can boot to if trouble happens.You can boot to any snapshot at any time. I personally have been using this to trial different security softwares.My screenshot shows as a trial ,but have purchased and have 4 snapshots available to boot into.
