关键参数解释：
rsync --help|grep bwlimit
--bwlimit=KBPS limit I/O bandwidth; KBytes per second
--progress show progress during transfer
--include=PATTERN don't exclude files matching PATTERN
--port=PORT specify double-colon alternate port number
sent 21 bytes received 20 bytes 5.47 bytes/sec
total size is 0 speedup is 0.00
最后,
实际用时可能还会加入Crontab：
每半个小时同步一下
crontab -u root -e
0,30 * * * * 写成一个shell去执行。
可能会出现问题：
view plainprint?
