In the transmitted in both directions (File Transfer Protocol, FTP) of the control file on Internet, and a kind of more transmission associations
It discusses one or more in (FTP-SSL or FTP-over-SSL, FTPS) etc..Wherein, TELNET application layer protocols are Intenet
The standard agreement and principal mode of remote login service.The account number cipher of login is transmitted with data clear text, is not encrypted.SSH is acted on
Ibid.Because transmission is encrypted, data are widely used simultaneously through benefits such as overcompression.SSH is initially a journey on unix system
Sequence was rapidly spread to other operating platforms again later.And FTPS is equivalent to the FTP of encrypted version, default port number is 21.In safety
Socket layer increases SSL using a kind of enhanced File Transfer Protocol of the File Transfer Protocol and instruction of standard for File Transfer Protocol and data channel
Security function.SSL is that data are encrypted in a secure connection between client computer and server with SSL functions
With the agreement of decryption.
Due to carrying File Transfer Protocol configuration information in backup instruction information, to be had sent to backup server
After backup instruction information, backup server and server to be backed up all can carry out file biography according to File Transfer Protocol configuration information
Transmission ＆ distribution are set, and the file transmission link between backup server and server to be backed up is established.Such as：Transport protocol is FTPS, is passed
