The boot partition...is C:.
On each of my two systems, I have made C: 20-25GB, no larger.
Soooo...when I backup, I only have a 25GB partition to back up.
If your C: partition is 200GB, I would suggest that you reduce the size....create at least one other partition...and move all data files from C:.
Or obtain an additional hard drive, create a data partition on it...and move your data files from C:. You can then downsize C: to the point where it is very easy to backup or clone.
Or...alternatively...clone your entire 200GB partition/drive...to another hard drive as a backup.
If you can take a picture of the Disk Management screen and attach it to your next post...it will save a lot of time and we can figure out what might be best for you.
My apologies...I see that you state that you have 1 hard drive, with a recovery partition of 13GB and one boot/system partition of 285GB. I don't know how to handle the recovery partition but I suspect that you need to consider that in your backup strategy, since the files on there may be required to restore your system in accordance with the manufacturer's instructions.
