iCloud Storage Confusion
HOpefully someone can explain about the iCloud backup/storage?
My MacbookAir has a 500 GB HD - looking at Storage I see I have only 18 GB available. But when looking at the HD, it shows about 300 GB of the drive says iCloud. But I thought iCould was stuff NOT on my Hard drive, but rather in the Cloud. When I go to my iCloud account, I see very little there - just a few docs, a few photos, and less that 20GB being used.
SO what's going on - is everything on my HArd drive? And where are the backups I've been making, supposedly to iCloud? I AM making backups via TIme Machine as well to an external HD.
Can someone help me out here?
Add: My computer currently goes to sleep every few minutes, but then wakes up maybe 10 - 15 seconds later. RUnning Diagnostics showed no issues. Could that be because the HD is so full?
THANK YOU
MacBook Air 13″, macOS 10.14
