About OpenSSH SFTP server
OpenSSH SFTP server is not a separate application. It is the built-in SFTP subsystem of the OpenSSH daemon, sshd, which ships with almost every Linux distribution, macOS, and Windows Server. It provides encrypted file access and transfer using the SSH File Transfer Protocol. Many backup tools rely on it as their remote storage endpoint.
The SFTP server supports chroot jails for restricted user directories, public key authentication, and integration with PAM or LDAP. It is part of the OpenBSD project and is maintained by the same team. Because it runs as a subsystem of sshd, configuration is done in sshd_config with directives like Subsystem sftp internal-sftp.
System administrators and backup software vendors use it as a reliable, audited, and zero-cost file transfer layer. It is open source under a BSD license. The SFTP protocol alone does not provide snapshots or deduplication, so it is best paired with a backup tool that handles versioning and compression on the client side.
