Can I back up my iMac files to Dropbox, using Time Machine, rather than to an external hard drive?
Although I back up to a 2-TB external hard drive, using Time Machine, the drive fills up, so backups only go back about 4 months. I've noticed that some files on my iMac have disappeared - and probably did so more than 4 months ago - so they're lost. What I'd like to do is back up to DropBox, instead of to the hard drive, and pay for the extra space there, so that I can go back farther than just four months. Is this possible? Thank you!
iMac 27″, macOS 10.14
