Difference with SFTP and FTPS?
The difference with SFTP and FTPS is very minor but achieves the same results. Encrypted file transfers. FTPS is FTP with SSL for security. It uses a control channel and opens new connections for the data transfer. Thus, it uses multiple ports. This uses SSL, and it requires an SSL certificate.
SFTP (SSH File Transfer Protocol/Secure File Transfer Protocol) was designed as an extension of SSH to provide file transfer capability, so it usually uses only the SSH port for both data and control.
Is SFTP or FTPS more secure?
Both are just as secure. They just use different methods to transfer data securely using SSL.
Technically, SFTP is easier for the backup setup firewall jargon. But it has nothing to do with the end-user. Most importantly the data is encrypted over a secure channel. They are however completely different protocols but achieve the same end result. Encrypted file transfers.
