Incidentally making frequent image backups seems a bit OCD-ish
I won't argue I'm OCD......
but as the former CEO of Intel (Andy Grove) said/wrote "only the paranoid survive".
To be honest, you can do "on-disk recovery" methods (eg. System Restore, RollBack RX, etc.) but the reality is HDDs
will (not if) fail.....it is just a matter of time. You need to be protected for as they call it "bare metal recovery"........meaning new HDD in PC and re-image. This will happen.....forget about just Virus or bad driver installs, etc......and if you don't have an external image of your HDD you lose everything. Obviously, with the new "cloud" world you can/should have your important "docs" backed up in the cloud. Bottom line, is just live Virus/Malware protection.....having backup protection is a layered approach. I once read a good instructional manual and the commentary within in it stated "I'm often asked how often should I back things up ?.........my answer is simple.....exactly how much of your data/info since last backup are you willing to lose forever.".
As
1234ava states.........System Restore is great to have/use and is helpful but FAR from getting you out of all jams....if you depend on it solely then you are definitely running with blinders on.
