Hi winnieyan,
How big is the emailed backup? It will tell you in the log.
Anything bigger than 25 MB can sometimes fail to email, as some hosts have limits on what they’ll send. Other hosts have limits on what they’ll receive too (gmail for instance won’t receive more than 25MB last I checked.)
So just check size. If the plugin says successful it means the email was submitted. But it still may have been rejected for delivery – we just don’t get notification of this so can’t report on it.

Thank you! It is the problem of the mail size! I have changed another email address and got the backup now!
