Web集群之全網備份腳本

module ucc creat eat awk ron ech pass 日誌 需求：實現指定目錄或文件定時打包到本地的/backup目錄以本機IP命名的目錄下，並且對打包的文件做md5哈希，然後將哈希的結果寫入到當前目錄下md5.log文件中，然後將打包的文件推送到backup服務端；還得將7天前的備份文件給刪除，每一步的操作都寫入到日誌中
備份的目錄/文件：var/spool/cron/root server/scripts/ etc/hosts etc/sysconfig/iptables var/log/
打包存放目錄：/backup/10.0.0.31
日誌文件目錄：/tmp/backup.log
rsync認證賬戶：rsync_backup
rsync認證模塊：backup
rsync認證密碼：123456
腳本可以在優化幾個點：
1）日誌內容太多怎麽辦？（可以統計日誌內容的行數，超過一定值，進行清空）
2）對打包的文件是否打包成功做判斷
腳本如下：
