实例：监测某文件夹，一旦文件夹里有文件，就把它剪切到其他服务器

import sys
import os, shutil
import time
import logging
from watchdog.observers import Observer
from watchdog.events import (LoggingEventHandler, FileSystemEventHandler)


backupDir = 'D:/Work/backup'
baseDir = 'S:/Test/Upload'

def copyFile(fromFile, toDir):
    if os.path.isdir(fromFile):
        clearDir = fromFile[len(baseDir):]
        try:
            os.makedirs(toDir + clearDir)
            print 'NewFolder: ', fromFile.encode('utf-8'), ' ===> ', (toDir + fromFile[len(baseDir):]).encode('utf-8')
        except:
            print 'NewFolder-PASS:', fromFile.encode('utf-8')
            return
    else:
        clearDir = os.path.dirname(fromFile)[len(baseDir):]
        if not os.path.isdir(toDir + clearDir):
            os.makedirs(toDir + clearDir)
        try:
            time.sleep(0.2)
            shutil.move(fromFile, toDir + fromFile[len(baseDir):])
            print 'MoveFile: ', fromFile.encode('utf-8'), ' ===> ', (toDir + fromFile[len(baseDir):]).encode('utf-8')
        except:
            print 'MoveFile-PASS:', fromFile.encode('utf-8')
            return

    return


class TestEventHandler(FileSystemEventHandler):
    def on_any_event(self, event):
        # print("event noticed: " + event.event_type + 
        #              " on file " + event.src_path.encode('utf-8') + " at " + time.asctime())
        pass

    def __init__(self, pattern='*'):
        self.pattern = pattern

    def on_moved(self, event):
        print ("moved src path:"+ event.src_path.encode('utf-8'))
        print ("moved dest path:"+ event.dest_path)
        copyFile(event.dest_path, backupDir)

    def on_created(self, event):
        print ("created path:"+ event.src_path.encode('utf-8'))
        copyFile(event.src_path, backupDir)

    def on_deleted(self, event):
        print ("deleted path:"+ event.src_path.encode('utf-8'))

    def should_reload(self, event):
        if isinstance(event, FileSystemMovedEvent):
            return True
        return False

    def on_modified(self, event):
        print ("modified path:"+ event.src_path.encode('utf-8'))
        copyFile(event.src_path, backupDir)


if __name__ == "__main__":
    logging.basicConfig(level=logging.INFO,
                        format='%(asctime)s - %(message)s',
                        datefmt='%Y-%m-%d %H:%M:%S')
    # path = sys.argv[1] if len(sys.argv) > 1 else '.'

    # event_handler = LoggingEventHandler()
    event_handler = TestEventHandler()
    observer = Observer()
    observer.schedule(event_handler, baseDir, recursive=True)
    observer.start()
    try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        observer.stop()
    observer.join()

补充一点：程序最终的效果，监测文件夹一旦有文件，就立马剪切到备份路径下，但是检测位置里的文件夹将不会被删除
