tar命令备份压缩7天生产日志

[root@localhost logs]# cat tar_7day.sh

#!/bin/bash

#压缩日期【当天的前一天】

todayStamp_1=`date -d "-1 day" +%Y%m%d`

#压缩日期【当天的前七天】

sevendaysagoStamp=`date -d "-7 day" +%Y%m%d`

Dirname=/mnt/Dirn_ame

Compressed_name=`ls $Dirname/*.log|awk -F '.' '{print $1}'`

 

#压缩7天日志

[[ -d $Dirname ]] && cd $Dirname && find . -name "*" -mtime -7 -type f |xargs tar -zcvf ${Compressed_name}${sevendaysagoStamp}-${todayStamp_1}.tar.gz

if [ ! -d backup ];then
  mkdir backup && mv ${Compressed_name}${sevendaysagoStamp}-${todayStamp_1}.tar.gz backup/
else
  mv ${Compressed_name}${sevendaysagoStamp}-${todayStamp_1}.tar.gz backup/
fi

sleep 2

# find命令find后面如果是.[当前目录缩写，那么后面的排除目录也必须是缩写，否则不生效]；如果是全量目录${Dirname}，那么后面的排除目录也必须是全量目录，如果是缩写就不生效。

[[ -d $Dirname ]] && cd $Dirname && find . ! -path "./*.tar.gz" ! -path "./*.log" -name "*" -mtime -7 -type f |xargs rm -rf

 

以上就是压缩脚本

被压缩目录为：

[root@localhost logs]# ll /mnt/Dirn_ame/
