python定時備份oracle數據庫上傳到ftp

利用python定時備份數據庫並上傳到ftp，代碼： 

import os;
import time;
import tarfile;
import shutil;
import ftplib;
import datetime

dumpdir = 'D:/oraclebak/';#oracle dmp的存儲路徑
tardir = 'D:/dumptar/'
dbList = ('user1','user2','user3');#oralce用戶
ftpdir = '/ftp/dump/';#ftp存儲路徑
##循環執行oracle備份命令
for dbname in dbList:
	command = "expdp userid='sys/syshaha@localhost/orcl as sysdba' \
                  directory=DUMP_DIR dumpfile=%s.dmp,logfile=%s.log schemas=%s" %(dbname,dbname,dbname);
	os.system(command);
	
tar_file = time.strftime('%Y-%m-%d_%H-%M-%S')+'.tar.gz';#建立tar文件

tar = tarfile.open(tardir+tar_file,'w:gz');

##循環將dmp文件壓縮到tar文件，而後刪除dmp文件
for root,dir,files in os.walk(dumpdir):
    for file in files:
        fullpath = os.path.join(root,file);
        tar.add(fullpath,arcname=file);
        if os.path.isfile(fullpath):
            os.remove(fullpath);
        elif os.path.isdir(fullpath):
            shutil.rmtree(fullpath,True);
tar.close();

## 上傳到ftp
ftp = ftplib.FTP();
ftp.connect('192.168.10.6','21');
ftp.login('dump','dumphaha');

#根據月份建立目錄
monthdir = time.strftime('%Y%m');

try:
    ftp.cwd(ftpdir+monthdir);
except ftplib.error_perm:
    ftp.mkd(ftpdir+monthdir);
    ftp.cwd(ftpdir+monthdir);
    
f = open(tardir+tar_file,'rb');
#print tar_file
ftp.storbinary('STOR '+tar_file,f);
f.close();

##刪除上一月份的備份文件，以減小ftp存儲空間
lastmonthdir = '';
lastmonth = datetime.date.today().month-1
if lastmonth<10:
    lastmonthdir = str(datetime.date.today().year)+'0'+str(lastmonth);
elif lastmonth == 0:
    lastmonthdir = str(datetime.date.today().year-1)+ '12';
else:
    lastmonthdir = str(datetime.date.today().year)+ str(lastmonth);
#print lastmonthdir;
try:
    ftp.cwd(ftpdir+ lastmonthdir);
    for lastfile in ftp.nlst():
        try:
            #print lashfile
            ftp.delete(lastfile);
        except Exception,e:
            ftp.rmd(ftpdir+lastmonthdir);
            print e;
            #ftp.rmd(lastfile);
    ftp.rmd(ftpdir+ lastmonthdir);
except ftplib.error_perm,e:
    print e;
ftp.quit();
os.remove(tardir+tar_file);

window下定製執行python

將以上代碼保存爲.py文件，而後設置window任務計劃程序
