Jestertheclown, indeed you and others have other procedures on how to keep your valuable personal data safe. If it works for you, GREAT! I tried decades ago under Windows system to keep documents on another drive (no C

. It was confusing and cumbersome to operate in. I used to do that in part to protect against too frequent system drive failures either hardware, blue screens or virus exposures. Some of that drove me to move to Mac OS. About 15 years ago I was basically using your plan with Windows and using NAS storage. I almost lost everything. I was down to 1 last viable copy of all my files. Today I feel 5 copies is just right.
I use a Mac Mini. I keep all the files/data I need (not talking archived data) on my system drive under documents folder. I replicate documents to iCloud which are instantly available to my MacBook, iPhone and iPad. To me that is a very important aspect. I do not want files with different versions floating around which becomes very time consuming to sort out.
I also use 2 portable USB external TimeMachine dedicated drives. I rotate backup between the two every week. Recently added/edit files are on the cloud or the trash can should I need them. NOTE: I also archive current and old files on other external drives using files sync app. Basically I have 3 copies of archived files and at least 5 copies of critical to me current files.
If something catastrophic happens ie house fire, I grab one of the drives before I leave. In case of theft, iCloud protects my photos, home videos, music and documents. That’s all I really care for.
I recently replaced the SSD drive on my MacBook. I fully restored the drive of all system file, applications, setting and all data within a couple of hours. Unless you are extremely organized, you will probably find apps and settings you forgot to address 6 months ago when you replaced your drive.
As you can see I’m a Mac user. I am sure there are good TimeMachine equivalent apps available in Windows environment.
Cheers
