I've been really struggling, having the time to update my secondary fdisr snapshot. I was thinking of a way to keep my snapshot updated but the choice of going back a day at the same time. Here's my idea: Primary Snapshot(Live System) 2nd and 3rd Snapshot. I setup a schedule that on Monday, Wednesday and Friday my 2nd snapshot is updated automatically and on Tuesday and Thursday my 3rd snapshot is updated automatically. That way if I want to go back a day I can but either way i have a snapshot up to date and a day behind. I keep forgetting to manually update my secondary snapshot and this might be a viable method to keep things updated but is costly in hard drive space.
