实际效果：假设给定目录"/media/data/programmer/project/python" ，备份路径"/home/diegoyun/backup/“ ， 则会将python目录下的文件按照全路经备份到备份路径下，形如：

/home/diegoyun/backup/yyyymmddHHMMSS/python/xxx/yyy/zzz.....

复制代码 代码如下:

importos

importshutil

importdatetime

defmainLogic():

#adddirsyouwanttocopy

backdir="I:backup"

copydirs=[]

copydirs.append("D:programmer")

copydirs.append("D:diegoyun")

print"Copyingfiles==================="

start=datetime.datetime.now()

#genadatafolderforbackup

backdir=os.path.join(backdir,start.strftime("%Y-%m-%d"))

#print"backdiris:"+backdir

kc=0

fordincopydirs:

kc=kc+copyFiles(d,backdir)

end=datetime.datetime.now()

print"Finished!==================="

print"Totalfiles:"+str(kc)

print"Elapsedtime:"+str((end-start).seconds)+"seconds"

defcopyFiles(copydir,backdir):

prefix=getPathPrefix(copydir)

#print"prefixis:"+prefix

i=0

fordirpath,dirnames,filenamesinos.walk(copydir):

fornameinfilenames:

print"backdiris:"+backdir

newpath=os.path.join(backdir,newpath)

print"newpathis:"+newpath

ifos.path.exists(newpath)!=True:

os.makedirs(newpath)

newpath=os.path.join(newpath,name)

print"From:"+oldpath+"to:"+newpath

shutil.copyfile(oldpath,newpath)

i=i+1

returni

defgetPathPrefix(fullpath):

#Giving/media/data/programmer/project/,gettheprefix

#/media/data/programmer/

l=fullpath.split(os.path.sep)

#printstr(l[-1]=="")
