Hi ABC. I'm Greg, 10 years awarded Windows MVP, here to help you.

How are you planning to mirror a partition? Normally mirroring is for an entire drive, like RAID1 mirrors. However I don't recommend it because I've seen too many lost files when one drive dies and the files are lost. You're better off with real time backup to the cloud along with periodic backup imaging using an app like free Macrium Reflect.

However if you still want to mirror a volume, I'd for sure have another backup method in case you lose both drives. Mirroring means exactly what it says, it exactly mirrors the changes you make on one drive to the other. Here is how to mirror a volume in Windows 10:
