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_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
