Junos OS provides a configuration archival feature to help network administrators to take a backup of the device configurations for disaster recovery or historical records purposes. The archival process can be configured to transfer the configuration file to a remote location periodically or when specific events occur, such as a commit operation.
The configuration archival feature in Junos OS supports several transfer methods. The two transfer methods that are available are:
TFTP (Trivial File Transfer Protocol) - TFTP is a simple file transfer protocol that uses UDP (User Datagram Protocol) for data transmission. TFTP does not support encryption, so it is not recommended for use in a secure environment. TFTP is typically used for transferring small files, such as configuration files.
FTP (File Transfer Protocol) - FTP is a widely used protocol for transferring files over the Internet. It uses TCP (Transmission Control Protocol) for data transmission and supports encryption for secure file transfer. FTP is suitable for transferring large files, such as software images.
In addition to TFTP and FTP, the configuration archival feature in Junos OS also supports the following transfer methods:
SCP (Secure Copy Protocol) - SCP is a secure file transfer protocol that uses SSH (Secure Shell) for encryption. SCP is similar to the traditional Unix cp (copy) command and supports copying files between hosts on a network.
SFTP (Secure File Transfer Protocol) - SFTP is a secure file transfer protocol that uses SSH for encryption. SFTP is similar to FTP but provides more security features, such as data integrity checks and strong authentication.
In summary, the configuration archival feature in Junos OS supports several transfer methods, including TFTP, FTP, SCP, and SFTP. The selection of the transfer method depends on the security requirements, file size, and network environment.
