Email logs Success but backup failed


today I’ve received email logs of a files backup with “success” in the object:

UrBackup: Incremental file backup of “srvma” - success

But When I analize the email:

UrBackup just did an incremental file backup of “srvmail01”.

( 20 infos, 11291 warnings, 1911 errors)

Why the subject is “SUCCESS” ?

My best regards
