Question
Is it possible to to compress the data being transferred on an FTP data connection?
Answer
Yes, it is possible to compress the data being transferred on an FTP data connection.
Use the COMpress subcommand (with no parameters) to set the data transfer mode to compressed mode. The COMpress subcommand is equivalent to specifying the MOde C subcommand.
In compressed mode, data is transmitted as a series of data blocks, preceded by one or more header bytes. Compressed mode preserves the logical record boundaries of the data set or file. In compressed mode, data is transmitted without repetitive characters and blanks. When MOde is set to C, the data transfer type must be EBCDIC.
Note: Because additional processing time is required for both the sender and receiver to compress or decompress the data, evaluate the time factor before you compress a file.
Data compression increases CPU processing costs even if the amount of data transferred is not large.
