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.

1. #!/bin/sh 
2. log_path=/tmp 
3. echo ===========Start-date=================  >> $log_path/backup.log 
4. date                                   >> $log_path/backup.log 
5. source_path=/tmp/liangtest/shell 
6. folder_name=bk 
7. target_path=/tmp/liangtest/shell2 
8. bakup_date=`date "+%Y_%-m_%-d_%H_%M"` 
9. echo "Backup Date ${bakup_date}"                           >>$log_path/backup.log 
10. mkdir $target_path/${folder_name}_$bakup_date                 >>$log_path/backup.log 
11. cp $source_path/$folder_name/*  $target_path/${folder_name}_$bakup_date 
12. sleep 5 
13. source_size=`du -sm $source_path/$folder_name` 
14. target_size=`du -sm $target_path/${folder_name}_$bakup_date` 
15. echo "source_size ${source_size}"                           >>$log_path/backup.log 
16. echo "target_size ${target_size}"                           >>$log_path/backup.log 
17. so=`echo $target_size|awk '{print $1;}'` 
18. ta=`echo $target_size|awk '{print $1;}'` 
19. if [ $so -eq  $ta ]; then 
20.         echo "Backup Done" $bakup_date                  >>$log_path/backup.log 
21. else 
22.         echo "Backup Failure!!!!"                          >>$log_path/backup.log 
23. fi 
24. ####Starting Compress#### 
25. echo ==========Starting Compress============    >> $log_path/backup.log 
26. date                                        >> /tmp/backup.log 
27. if 
28. cd $target_path/${folder_name}_$bakup_date 
29. tar -cvzf $target_path/${folder_name}_Compressed_$bakup_date  * 
30. then 
31. cd $target_path 
32. rm -rf  $target_path/${folder_name}_$bakup_date 
33. echo "Backup Done,Delete folder Success!!!"  $bakup_date    >>$log_path/backup.log 
34. else 
35. echo "Compress Failure!!!!"                                  >>$log_path/backup.log 
36. fi 
37. echo ===========End-date=================    >> $log_path/backup.log 
38. date                                                      >> $log_path/backup.log 

The output for log as below

1. ===========Start-date================= 
2. Sun Jul 15 14:42:23 CST 2012 
3. Backup Date 2012_7_15_14_42 
4. source_size 2   /tmp/liangtest/shell/bk 
5. target_size 2   /tmp/liangtest/shell2/bk_2012_7_15_14_42 
6. Backup Done 2012_7_15_14_42 
7. ===========Starting Compress===========
