Hi there
speed of CPU actually doesn't play a huge role in this -- the I/O device capability is the limiting factor here.
However even with spinners you ought to be getting around 300 Mb/s or around 80 MB/s. So do the maths -- 800 MB will take around 10 secs, 8GB around 100 secs and 800GB will take 10000 secs or around 3 hrs.
If you are using USB2 or really slow spinners say 30 Mb/s then you are going to take a long long time -- on the macrium log it should give you read / write I/O rate. Without that we can't say if you've got a mega problem or not.
just start Macrium up again from within Windows and after it's done the recovery and small partitions note what the I/O rate is when it's backing up the big partition -- you can cancel it after say 5 or 10 mins once it's settled down to a reasonably constant I/O rate. Divide by 4 the Mb/s rate shown to get MB/s.

Hi there
@f14tomcat
even on an i3 that´s not an issue
Over my years with computers the biggest bottleneck to throughput has been hideously slow I/O.
So many people just don't realize it -- but even a so called lowly i3 processor has more compute power than the entire computing / electronics industry combined might of Germany, Japan,USA + allies and Russia in 2nd world war combined !!!.
I often complain about UK here but the unsung real hero in this was a person called Tommy Flowers who worked for GPO ( Post office in UK at that time a Govt organisation) -- he invented electronic switching but at his own expense and his stuff was never allowed to make public domain until foreign newspapers published some of his stuff after the war (WWII)
Tommy Flowers - Wikipedia
Everbody with any interest in History has heard of Bletchley park where people were employed to decrypt German Enigma machine code -- initially done mechanically via things called Bombes (no typo that is what they were called) -- Flowers invention speeded up the process absolutely dramatically.
After the end of WWII there was a lot of problem between USA and GB on this technology -- not even sure if today it's been settled between the 2 most steadfast allies on the planet.
Anyway if you are interested :

Also great stuff from NASA in 1960's with Voyager satellites -- now still sending stuff back to earth at edge of interstellar space -- at incredibly slow bit rates -- you have to admire those early pioneers though.
Voyager
Any capable intel processor would merely be idling at average I/O speeds on slow HDD's -- and as for IDE -- you might just as well use paper tape flexowriters -- remember those !!!

Also would like to add that regular hdd I think you refer too as spinners are not all that slow if you have a SATA III hdd on a SATA III port. I have two nearly identical drives, one that is SATA III on a SATA II port as my old motherboard only has two SATA III ports. The one on the SATA II port is like molasses compared to the even larger spinner on the SATA III port.
I had the one being slower now in the SATA III port until I added a new larger hdd for backups. I wanted my backup restore to be faster so I put it the new hdd on the SATA III. I can say for 100% sure, the difference in speed is major for the two. I know how fast the other one was on the SATA III port before I got the new one. It is not SSD fast by any means, but the SATA III will make a major difference even if the spinner is 5400 rpm. It does for me.
OP asked about background programs and utilities earlier. Yes, such can add time to the backup & verify process -- I'm guessing that Windows "time-slices" rather than really doing several things at the same time. During serious backup routines, I will turn off any EZ-to-turn off stuff, disconnect from The 'Net and turn off AV/AM, and so on.
