I think there several issues/tickets/changes here: 1- Replace zlib with zstd for over-the-wire compression client communication 2- Replace zlib with zstd in gbak (really nice to have in v4.0) 3- Add zstd compression to nbackup (really nice to have in v4.0) 4- Adding support for compression libraries/plugins for over-the-wire compression 5- Adding support for compression libraries/plugins to gbak 6- Adding support for compression libraries/plugins to nbackup I am happy to create Tracker entries, if there is agreement.
