Can I Sync FTP to S3 Easily?


I notice that many software can connect FTP servers and AWS S3 separately but none of these tools seem to be able to sync a remote FTP server to S3 without downloading files from FTP to local first. Is there any service that I can use to sync FTP with S3 easily?

According to the current situation, the vast majority of IT professionals and business users trust FTP (File Transfer Protocol). These users have been using this kind of protocol to transfer files in certain computer networks for some time. FTP is easy and free to use for work. It can be run anywhere and configured for automation. 

But on the other side, with the development of cloud technology, lots of cloud storage services are bringing innovations and opportunities. Among these services, the cloud-based AWS S3 bucket storage, which can help you handle different transfer protocols well, may be all you need.

If you are both an FTP user and an Amazon S3 user and want to use the same files conveniently in these two services, you can learn how to set up FTP to S3 sync by using the simplest and most reliable method listed below. Besides, instead of leaving your important business data wide open to the FTP, you can also sync the FTP server to Amazon S3 to let FTP backup to Amazon S3 without any risk of data loss.
