根据Informix的说法，onbar具有比ontape更好的功能；它可以执行并行备份和恢复，将对整体性能有益。
During a parallel backup, whether it is a standard backup (onbar -b) or whole-system backup (onbar -b -w), multiple processes run simultaneously and back up data to separate dbspaces.
在并行备份期间，不管是标准备份(onbar -b)还是全系统备份(onbar - b- w)，都是多个进程同时运行，并将数据备份到不同的dbspace中。
