System Restore on each hard drive?

[TwixOps]

I'm setting up system restore on my Win 10 pro PC, and I'm confused about whether I need to allocate space on each hard drive for the restore points.  

My system has:

120 GB SSD for the boot drive,

a pair of 2 TB HDD in RAID 1 for program installation

1 500 gig for media.  

 

 

Do I need to allocate space on each drive for  the restore points?  How much?

It's set by the percentage of how much you want to reserve for restore point. By default only the OS drive gets turned on. The rest has to be turn on manually. In that, use the slider to adjust how much you want to set.

only allocate space for drives with files that you want rolled back with system restore points....otherwise do a manual backup to an external medie (like a HDD or DVD/BluRay)

People use system restore? I remember back in the day viruses and shit used to Hide in system restore. So Ive never used it.
