History In part 1 of this series I discussed why I desired a computer setup where I can do full system snapshots so I could seamlessly roll back at will. I also gave an overview of how I went about setting up a system so it could take advantage of BTRFS and snapper to do full system snapshotting and recovery. In this final post of the series I will give an overview of how to get snapper installed and configured on the system and walk through using it to do a rollback.
