import os 
import time 
import string 

source=['/var/www/html/xxx1/','/var/www/html/xxx2/'] 
target_dir='/backup/' 
target=target_dir+time.strftime('%Y%m%d') 
zip_comm='zip -r %s %s'%(target," ".join(source)) 

target_database=['DB_name1','DB_name2'] 
sql_user='root' 
sql_pwd='xxx' 

if os.system(zip_comm) == 0: 
print 'file backup Success is:',target 
#if python version is 3.x ,print('file backup Success is:',target) 
else: 
print 'file backup failed!' 

for database_name in target_database: 
target_sql=target_dir+database_name+time.strftime('%Y%m%d')+'.sql' 
sql_comm='/usr/local/mysql/bin/mysqldump -u %s -p%s %s > %s'%(sql_user,sql_pwd,database_name,target_sql) 
if os.system(sql_comm) == 0: 
print database_name,'is backup seccess!'
