Can I back up an external drive to the iCloud?
Hi. I have an external Seagate 2TB drive with my faily home movies saved onto it.
Can I copy this into iCloud?
My iMac is quite old, running OS Catalina 10.16.7
iMac 21.5″, macOS 10.15
What mulberry58 was saying is that iCloud isn't the best choice of places to "store" something. iCloud's purpose is to make it easy to change files from any device or any computer.
If that's what you want, rather than an actual backup, then you would need to drag the contents of your 1TB drive into the iCloud Drive on your Mac. iCloud Drive at iCloud.com is a copy of that iCloud Drive that's on your Mac.
All your files in iCloud Drive may not be local to your Mac all the time, so Time Machine backups may not include all of your iCloud Drive files.
