I've never wanted that sort of backup in the last 20 years of computer usage. I think it's a bit old fashioned honestly. Nowadays a computer is an ephemeral thing; all that's persistent is files in the cloud, git repos, and provisioning config to get a new machine in a similar state to the last one. And yes I know "similar" there will have made your heart skip a beat :)
One last point. A backup shouldn't be "a special local folder" - it should be "all files on all drives unless I specifically exclude them"
