用python脚本对svn库进行备份,压缩,加密,ftp上传

import logging
import os,sys
import tarfile,bz2
import time
import shutil
import subprocess
from ftplib import FTP

#

# 必要条件

# 1.安装Python

# 2.对GnuPG要求

# A.安装GnuPG且执行目录配在PATH内

# B.导入加密用户的公钥

# C:\..\> gpg --import svnbackup-public-key.txt

# C.对加密用户绝对信任

# C:\..\> gpg --edit-key svnbackup

# Command> trust

# ....

# ....

# 请选择 5

# ....

# Command> quit

# 3.启动"定时作业"程序

# 4.设置"定时作业",由于都为全量备份,最好不要设置每星期都执行,可以一星期执行一次

# C:\..\> at 05:00 /every:M,T,W,Th,F,S,Su f:\svndepository\backupsvn.bat

# C:\..\> at 23:30 /every:F f:\svndepository\backupsvn.bat

#

# 5.生成backupsvn.bat文件

# 内容如下:

# set USERPROFILE=C:\Documents and Settings\Administrator

# c:\Python24\python f:\svndepository\svnbackup.py

#

# 其中环境变量%USERPROFILE%是gpg所需要的 

#

global_log='F:\\svnbackup\\svnbackup.log' #日志文件所在位置

global_crypt_person='svnbackup' #gpg public key所属的人

global_ftp_server='192.168.0.84' #ftp服务器的ip或名字

global_ftp_user='svnbackup' #ftp帐号

global_ftp_password='svnbackup' #ftp帐号对应的密码

global_destdir="F:\svnbackup\\" #备份所用的临时目录:最后的两个\\一定不能少
