sending sbackup reporting

I don't know how to send emails only when errors occur, but it can send emails every time backup happens.

Add following to /etc/sbackup.conf

[report]  
 from = SBackup Daemon   
 to = ****@gmail.com  
 smtpserver = smtp.gmail.com  
 smtpuser = ****@gmail.com  
 smtppassword = ****  
 smtpport = 587  
 smtptls = 1
