Re: Set "System-restore-point"?
Not having "System Restore" available in Linux can actually be viewed as a good thing -- as folks in Windows often assume this means restoring the "whole" system, when in fact, it does not. It's not a Time Machine; instead, when some upgrades get performed, Windows squirrels off copies of the system files being changed. When you do a System Restore, all it does then is overwrite some system files with those older copies.
Which is why many folks in Windows use imaging apps (like Acronis or Macrium Reflect) to make full system backups -- which do allow the restoration of the "whole" system.
You can, and should, consider doing the same thing using Clonezilla. It only takes a few minutes to run and can save you HOURS of work should you need to restore your system.
