There's potential for a date discrepancy.  To keep file names consistent you should set the date in a variable first and then call it.  When referencing variables you should use the newer bash format ${var} and when subshelling you should use $(command) rather than `command`.

e.g.
DATE="$(date +%m_%d-%y)"
/bin/tar -c -v --use-compress-program=pigz /mnt/drive_z/ \
         -f  /mnt/backupLUN09_SAN/file-server-backup--${DATE}--.tar.gz \
         1>  file-server-backup--${DATE}.index

Also, I second Rich's opinion in that you should use a real backup solution rather than jerry rigging it with tar+compression.
