I have an OS installed in VirtualBox and like how I can take a snapshot of the current state of the OS before making changes to it, from changing settings, to installing software, to applying updates, to anything.
Then if anything goes wrong, I can always revert back to the perfect snapshot I saved earlier.
What if I need similar functionality but outside of a virtual environment, i.e. on real physical hardware? For example, is there an quick and easy way of taking snapshots of the current computer you'er using, before making changes to it. Where you can easily revert back to how the software was by selecting the appropriate snapshot
