Data Compression and Fast Data Transfer?

» close window

The Question is:

 
We have approximately 50 large files on Alpha VMS that need to be FTPed as
 quickly as possible when they change.  However, their sizes are large -
 anywhere from 150,000 blocks to 25,000,000 blocks.  I am trying to find
 compression software that can reduce
 the file sizes more quickly than I can FTP the files.
 

The Answer is :

 
  The bzip, Info-ZIP and gzip compression tools are available on the
  OpenVMS Freeware.  Alternative approaches include tracking and
  transfering only the data differences, and not (unnecessarily)
  transfering any unchanged data -- various techniques used to encode
  video data could be of interest, too.  The use of the fastest available
  datalinks will have already been considered here, of course.
