Investigate if there is a way to get snapshots of systems, what are the benefits and the requirements.

The qemu snapshots do not seem to be the proper tool for what I would like to do. They require the system to use at least one qcow2 disk image, which can be restrictive to those who would like to have raw images or even a different physical hard disk.

Maybe I should develop my own snapshot system, which creates copies of the hard disks and has a way to manage them from the GUI. So the following features should be in place:

1. Create a snapshot. The system should not be in a running status. The snapshot should create copies of the hard disks and maybe use some kind of archiving (7zip can be used)
2. The user should be able to delete snapshots
3. The user should be able to restore a snapshot in place of the current one
4. Snapshots should have a proper date and time logged
5. There needs to be clear information for the user what a snapshot is and what happens, where the files are saved etc.
6. Maybe the snapshot should be able to happen in a different place
7. Maybe there should be a check if there is enough space to make a snapshot
8. Snapshots should not be able to be done on systems that use physical hard disks
