I doubt that NASA has a more comprehensive range of backup options - I certainly don't! There must be some mighty valuable data involved. I don't think you need to be concerned.
My own office routine involves automated data backups from all machines to external drives every 15 minutes. I use Avast anti-virus software and CCleaner is run every 48 hours on all machines.
I have never created a system image in a lifetime of working with computers, and I have never run system backups. My websites and those of my clients are running on a dedicated server in a data centre, and of course there are comprehensive backup routines in use there.
I can't really comment on the Microsoft technician's software choices - I have never used any of them.
