利用AWS boto实现EC2 存储卷的自动快照
boto是AWS的Python SDK,可以利用boto自动生成ec2的存储卷快照，实现ec2数据的备份1.安装boot
pip install boto ，如果没有安装pip,需要提前安装
2.配置boto配置文件
~/.aws/credentials#设置aws认证凭据
aws_access_key_id = AAAAAAAAAAAAAAA
aws_secret_access_key = TNAAAAXXXXXXXXXXXXXXXXXXXXXX ~/.aws/config #设置默认区域
region = us-east-1
3.编辑脚本
#Date:
#Author:
#Usage: python snap.py volume_id number_of_snapshots_to_keep
import boto
import sys
import pdb
from datetime import datetime
conn = boto.connect_ec2()
conn_us = conn
if len(sys.argv) < 2:
print "Usage: snap.py vol-id days-to-keep"
exit()
vol_id = sys.argv
keep = int(sys.argv)
volumes = conn_us.get_all_volumes()
volume = volumes
description = 'hostname' + '-' + datetime.today().isoformat(' ')#镜像描述
volume.create_snapshot(description)
snapshots = volume.snapshots()
def date_compare(snap1, snap2):
if snap1.start_time < snap2.start_time:
return -1
elif snap1.start_time == snap2.start_time:
return 0
return 1
snapshots.sort(date_compare)
delta = len(snapshots) - keep
for i in range(delta):
print 'Deleting snapshot ' + snapshots.description
try:
snapshots.delete()
except Exception, e:
pass
4.加入crontab
volum-id可以在控制台中找到
#每天凌晨自动生成磁盘快照
00 00 * * * python /opt/scripts/snap.py vol-00c69ee40b3ad1bf4 10 #Disk snap
