1. What is Rsync SSH Key? 🚀
Rsync SSH key is an amalgamation of two powerful technologies: rsync and SSH (Secure Shell). It combines the robust file synchronization capabilities of rsync with the secure encrypted communication provided by SSH.
SSH keys, also known as public-key cryptography, provide a secure method for authenticating and establishing encrypted connections between remote computers. In the context of rsync, utilizing SSH keys ensures that data transferred between the source and destination remains confidential and protected from unauthorized access.
1.1 How Does Rsync SSH Key Work? 🔐
Rsync SSH key employs a client-server model. The client initiates a secure SSH connection with the remote server using their private SSH key, ensuring a secure and encrypted channel for data transmission. Rsync then leverages the delta transfer algorithm, which effectively transfers only the differences between the source and destination files, minimizing bandwidth usage and optimizing transfer speeds.
