Knowledge of Dropbox and Amazon S3

As known, Dropbox is a cloud service that lets you sync files between your computers and mobile devices to bring your files, photos and videos anywhere and share them with others easily. Amazon S3, whose full name is Amazon Simple Storage Service, is a fully redundant data storage system. S3 makes it easy to store and retrieve any amount of data, anytime, from anywhere. Notice that we focus on Amazon S3, not Amazon Cloud Drive here, please click to learn what's the difference between Amazon Cloud Drive and S3.

Nothing is perfect, both Dropbox and Amazon S3 have advantages and disadvantages. So people use both of them.

Are you going to manually do it by downloading files to your local disk and re-uploading to your new service? Is a better way to do it, right? We recommend MultCloud to help you backup, sync and move files from Dropbox to Amazon S3.
