Handle error
I have a script as below , the script can tar file to the tape , however , it is fail to handle the error , if there is error like the backup file is in writing , then it will echo this is fail ( but the file has successful backup actually , so the backup task is succes , but it still report it is fail ) , can advise how to modify it so that if all files are backup , then echo this is success ? thanks

Code:
tar -zcvf /dev/st0 ...
if [ $? -eq 0 ] ;
	then echo this is success
else 
 echo this is fail

fi
