You should do real backups, that won't get corrupted by the same changes that corrupts your main system.
If you have some external dependency that takes your VM down, the image will be down too.
You should have multiple backups, at least one which is on a different medium/different location. Its absolutely fine to have a backup on the same machine, even the same hard drive as the working copy. As long as it is not the only one.
VM snapshots are a backup! Change my mind!
What? If your hypervisor shits the bed, you have bigger problems.
