You might want to try reducing those to only one. And, you might want to try a newer version. If you've got the disk space, you might try uncompressed tar and then gzip'ing the resulting archive. Also, you might try redirecting stdout and stderr to a file on the remote system to reduce the possibility that a bad connection over ssh might be hanging the process. Is it possible that a remote batch job is working in the /data area at the same time you're trying to do the backup? Don't know if any of this will help.
