Nowadays, the restoration software basically uses a one-Click Reset wizard or ghost on a personal computer, while the public computer restores the software on an ice. The latter charges fees, but it is easy to find the authorization code.
One-click Restore wizard and ghost are usually used for a long time to create a backup image. Freezing points can often be used for backup (for example, every two days), but restore points must be set, it is not easy to understand for new users.
When I was in the company today, my colleagues recommended "comodo time machine". I feel very good! Otherwise, I won't record it.
If you have used a VM, you should know the role and use of VM snapshots. comodo time machine is also based on that idea, just a host snapshot. When I was using it today, I found that after creating an original snapshot, I installed some software on the basis of it. When I took a snapshot, I found that the comodo time machine recorded the size of the new file. I guess comodo time machine is based on File Usage: Compare the current system environment with the original snapshot, such as adding, removing, modifying, and moving files. comodo time machine will be recorded, mostly databases are saved. This technology is amazing !!!
