Wait, there's an M.2 disk in an Exadata system? That's like putting a sports car engine in a forklift. I'm not sure if that's genius or just plain weird.

C is a bit strange. System area on the first two disks and M.2 devices? That's like storing your backup on the same device you're trying to back up. Seems risky to me.

E sounds like a good option, but I wonder how it compares to the traditional backup methods. Gotta do some research on that one.

D is a bit confusing. I thought the M.2 disks were hot-swappable, but I didn't know about the manual restore part. Interesting!
