Script for Python backup files _python

Actual effect: Assuming the given directory "/media/data/programmer/project/python" and the backup Path "/home/diegoyun/backup/", the files in the Python directory are backed up to the backup path by the entire path. Shaped like:

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

Copy Code code as follows:

Import OS
Import Shutil
Import datetime

Def mainlogic ():
#add dirs you want to copy
Backdir= "I:\\backup"
Copydirs=[]
Copydirs.append ("D:\\programmer")
Copydirs.append ("D:\\diegoyun")

print "Copying Files ==================="
Start=datetime.datetime.now ()

#gen a data folder for backup
Backdir=os.path.join (Backdir,start.strftime ("%y-%m-%d"))
#print "Backdir is:" +backdir


Kc=0
For D in Copydirs:
Kc=kc+copyfiles (D,backdir)

End=datetime.datetime.now ()
Print "finished! ==================="
Print "Total Files:" + str (KC)
Print "Elapsed time:" + str ((End-start). seconds) + "seconds"

def CopyFiles (Copydir,backdir):
Prefix=getpathprefix (Copydir)
#print "prefix is:" +prefix

For Dirpath,dirnames,filenames in Os.walk (copydir):
For name in filenames:

Newpath=omitprefix (Dirpath,prefix)
Print "Backdir is:" +backdir
Newpath=os.path.join (Backdir,newpath)
Print "NewPath is:" +newpath

If Os.path.exists (NewPath)!=true:
Os.makedirs (NewPath)
Newpath=os.path.join (Newpath,name)
print ' From: ' +oldpath+ ' to: ' +newpath

return I

def getpathprefix (FullPath):
#Giving/media/data/programmer/project/, get the prefix

#print Str (l[-1]== "")
