I have a question about backups. I am watching the course video Disaster Prevention & Recovery and they are talking about backups. They mention that you can do an image backup. So my question is, What if the system has malware? If you do an image backup and restore it does that restore everything including malware? Because I see a drawback when it comes to image backup.

Hey @John-Romeo great question and observation. The short answer is yes, if you take an image (bit-by-bit copy) the malware will be present in the image. A little more detail. The thought process behind any backup system (i.e. image, full, differential, incremental, or even VM snapshots) is to capture or prepare them in a "clean" configuration state. The VM snapshots are not for restoration in the traditional sense, this is performed to revert to a prior configuration state typically in test (non-production) environments.
1 - In home environments or workgroups (10 computers max.), you create a system image of the drive prior to use.
2 - In enterprise environments, the image is prepared from a fully configured desktop (applications, system configuration) called a reference machine into a master image that is deployed to the PC.Then once the image is captured then restoration will apply a fresh image back to the drive.
Great question!
