iCloud backup

Can anyone share their offsite back up strategy? I’m interested in learning if my Cubase files can be synched with iCloud. If not what is a good strategy for off site storage? I recently had my external HD crash and now in the process of trying to get the data recovered. Don’t want to make that mistake again.

Thanks in advance for sharing all your expertise and experience.
