Shell Script For Backup Folder

Recently, our team file server need to auto backup, so I write this script to back via contab.

This script is very easy, I just want save it for review later.

If it can help you, I will happy.

#!/bin/sh 

log_path=/tmp 

echo ===========Start-date=================  >> $log_path/backup.log 

date                                   >> $log_path/backup.log 

source_path=/tmp/liangtest/shell 

folder_name=bk 

target_path=/tmp/liangtest/shell2 

bakup_date=`date "+%Y_%-m_%-d_%H_%M"` 

echo "Backup Date ${bakup_date}"                           >>$log_path/backup.log 

mkdir $target_path/${folder_name}_$bakup_date                 >>$log_path/backup.log 

cp $source_path/$folder_name/*  $target_path/${folder_name}_$bakup_date 

sleep 5 

source_size=`du -sm $source_path/$folder_name` 

target_size=`du -sm $target_path/${folder_name}_$bakup_date` 

echo "source_size ${source_size}"                           >>$log_path/backup.log 

echo "target_size ${target_size}"                           >>$log_path/backup.log 

so=`echo $target_size|awk '{print $1;}'` 

ta=`echo $target_size|awk '{print $1;}'` 

if [ $so -eq  $ta ]; then 

        echo "Backup Done" $bakup_date                  >>$log_path/backup.log 

else 

        echo "Backup Failure!!!!"                          >>$log_path/backup.log 

fi 

####Starting Compress#### 

echo ==========Starting Compress============    >> $log_path/backup.log 

date                                        >> /tmp/backup.log 

if 

cd $target_path/${folder_name}_$bakup_date 

tar -cvzf $target_path/${folder_name}_Compressed_$bakup_date  * 

then 

cd $target_path 

rm -rf  $target_path/${folder_name}_$bakup_date 

echo "Backup Done,Delete folder Success!!!"  $bakup_date    >>$log_path/backup.log 

echo "Compress Failure!!!!"                                  >>$log_path/backup.log 

echo ===========End-date=================    >> $log_path/backup.log 

date                                                      >> $log_path/backup.log 

The output for log as below
