按时间区分备份日志

脚本如下

#!/bin/bash

## 源目录项目名称，需根据目录名进行调整
project_name=/logs/alarm/

## 源目录
basedir=/opt/logs/$project_name

## 备份目录
backdir=/opt/back_logs/

## 定义readme文件 记录备份文件
rr=/opt/back_logs/readme

## 创建备份目录
if [ ! -e $backdir ];then
    mkdir -p $backdir
fi

## 一个月前
to_date=`date -d "-1 month " +%Y-%m-%d`

## 源目录赋值变量
cd $basedir
for file in `ls $basedir`
do
## 截取日志属性时间值，按截取年月日创建目录，将源日志备份到对应时间的目录下
     y=`echo $file | awk -F'-' '{printf "%s-%s-%s\n",$3,$4,$5}' | awk -F'.' '{print $1}' |awk -F '-' '{print $1}'`
     m=`echo $file | awk -F'-' '{printf "%s-%s-%s\n",$3,$4,$5}' | awk -F'.' '{print $1}' |awk -F '-' '{print $2}'`
     day=`echo $file | awk -F'-' '{printf "%s-%s-%s\n",$3,$4,$5}' | awk -F'.' '{print $1}' |awk -F '-' '{print $3}'`
     #ls |cut -c16-25
      
## 一个月前
  if [[ $y-$m-$day > $to_date ]];then break;fi
       #echo $y-$m-$day $to_date
     if [ ! -e $backdir$file ];then
        tree $backdir >> $rr
        mkdir -p $backdir/$y/$m/$day/$project_name/ &> /dev/null
        cp $file $backdir/$y/$m/$day/$project_name/ &> /dev/null
        sum=`ls $backdir/$y/$m/$day$project_name/  |wc -l` &> /dev/null
   
         if [ $? -eq 0 ];then
             echo -en "----- \t\t\t" >> $rr
             echo `date` >> $rr
             echo -en "----- \t\t\t" >> $rr
             echo "$backdir$y/$m$project_name$day The backup OK" "Number of package $sum" >> $rr
         else
             echo -en "----- \t\t\t" >> $rr
             echo `date` >> $rr
             echo -en "----- \t\t\t" >> $rr
             echo "$backdir$y/$m$project_name$day The backup NO" "Number of package $sum" >> $rr               
         fi
    fi
done

## 备份日志上传到obs
/opt/case/obsutil/obsutil cp -r -f $backdir$y  obs://obs-log-archive/data/ >> $rr 2>&1  && echo "数据上传到obs成功" >> $rr || echo "数据上传到obs失败"  >> $rr
echo `date +%Y/%m/%d/%T` "script over!"  >> $rr

演示创建对应的日志路径与日志名，用于脚本测试

# cd basedir && touch alarm-2021-09-{01..31}.{1..31}.log.tar
