Apart from what Alan has recommended I would also recommend to write a
log file, using the -y switch, like in

gbak -b -t -v -user "username" -pas "password" -y "mylogfile.txt"
"source_database" "dest_file_path"

Make sure your log file does not exist before you start this because
GBAK will fail. I always put a DEL command before that.
