"I used it for a while, but I had to uninstall it. I have little understanding of how it works, so I crashed my system using it. Fortunately, I did not have anything on it that was irreplaceable. I have been using Mint since 17.1, but I have not delved deeply into it, so I have problems completely removing apps I no longer want to use. In Mint 19.x I used Timeshift a few times to take me back to the place before I installed certain apps, and it worked great. However, one day I choose an option that I did not fully understand, and it corrupted Grub so that I could no longer boot into Mint. This forced me to reinstall Mint, disable the warning message that system snapshots were not set up, and uninstall Timeshift. This is definitely not a tool for the uninformed user."
