• #!/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
  
• else
  
• echo "Compress Failure!!!!"                                  >>$log_path/backup.log
  
• fi
  
• echo ===========End-date=================                    >> $log_path/backup.log
  
• date                                                         >> $log_path/backup.log
