OK, in an  another scenario  I can see , "-t server" working with 
"--server-compression" option  but not with -z  or -Z ?

"-t  server" with option "-z"  / or (-Z )

[tushar@localhost bin]$ ./pg_basebackup -t server:/tmp/dataN -Xnone  -z  
--no-manifest -p 9033
pg_basebackup: error: only tar mode backups can be compressed
Try "pg_basebackup --help" for more information.

tushar@localhost bin]$ ./pg_basebackup -t server:/tmp/dataNa -Z 1    
-Xnone  --server-compression=gzip4  --no-manifest -p 9033
pg_basebackup: error: only tar mode backups can be compressed
Try "pg_basebackup --help" for more information.

"-t server" with "server-compression"  (working)

[tushar@localhost bin]$ ./pg_basebackup -t server:/tmp/dataN -Xnone  
--server-compression=gzip4  --no-manifest -p 9033
NOTICE:  WAL archiving is not enabled; you must ensure that all required 
WAL segments are copied through other means to complete the backup
