People backup a lot of data these days in the cloud: photos, videos, full system backups. Ideally, you wouldn’t trust a single cloud service as your sole off-site backup because you shouldn’t put all your eggs in one basket. So having your data on at least two clouds is recommended. Uploading your data twice though would take more time for you.
You may also need to transfer or copy files between different cloud services such as Google Drive and OneDrive. The long and hard way is to download the files first to a local computer and then once that’s done, upload these files to the other server. The more advanced way to do it is rsync.
rclone is the rsync for cloud storage and the easy way.
