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.
