Re: creating a restore point...?
Just so you know ... if you want something in Linux that works like System Restore does in Windows -- then you've probably been mislead to believe that System Restore is like a time machine, in that it restores your COMPUTER system back to a previous point in time.
Sadly, it does not do that. Instead, it restores the Operating System, and select components, to an older version. Your files and data are not touched, and also, NOT restored.
So, if you are using System Restore on Windows in order to completely restore your Windows PC to a previous time, you should consider an alternative (like Macrium Reflect, or Acronis Backup and Recovery) that really do image off the PC.
Ubuntu 16.04 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
