SFTP vs SCP: Which File Transfer Method Should You Use?

When it comes to transferring files securely between your local machine and a remote server, SFTP and SCP are the two most common options. Both run over SSH and encrypt your data in transit, but they differ significantly in features, performance, and use cases.

SCP: Simple and Fast

SCP (Secure Copy Protocol) is the simpler of the two. It copies files between hosts using SSH for encryption and authentication.

SFTP: Feature-Rich and Interactive

SFTP (SSH File Transfer Protocol) is a full-featured file transfer protocol built on top of SSH. Unlike SCP, SFTP provides an interactive session where you can browse remote directories, rename files, set permissions, and resume interrupted transfers.

Performance Comparison

In controlled benchmarks, SCP can be 10-20% faster than SFTP for large file transfers.

Which Should You Use?

Use SCP when you need a quick, one-line command. Use SFTP when you need to browse remote file systems.
