Python Backup Files

Recently wrote a python script to replace the previous shell script, found that Python is better than the shell of the most intuitive point python structure is clear, readable (I think) do some records here

This record uses Python Script
1,SVN Backup, Package Paramiko for SFTP and SSH connection and Ssh_exec_command

2. Delete outdated files

1,SVN Backup

Preparation: Python Paramiko Install

Method 1: Install directly using PIP

Pip Install Paramiko

Method 2: Download the source code to install

Paramiko-1.15.2.tar.gz Main Documents

ecdsa-0.13.tar.gz Dependent files

pycrypto-2.6.1.tar.gz Dependent files
