Duplicate Email Notifications for Agent Backup Copy Jobs

This looks unusual for a single copy job, especially since job-level notifications are disabled.

I would suggest checking the email side as well:

• Verify the recipient list in notification settings and ensure there are no duplicates or distribution groups that might expand to the same users multiple times
• Check if any email forwarding rules are configured on the recipient mailbox or at the Exchange/mail server level transport rule that could forward the email again

Hi ​@Nikks do you have to backup jobs in one copy job? Then explains it ....

Sorry Marcel, can you explain it more?

Checked nothing unusual with the settings. 

I think Backup Copy jobs for Agents behave differently from VM backup jobs:

They are policy‑driven

They run parent + child sessions

Each session independently triggers global notifications, so sending duplicate emails ?

https://helpcenter.veeam.com/docs/agentforwindows/userguide/integration_backup_copy.html?ver=13

A single Backup Copy run = multiple job sessions for Agents.

Can it be the reason ?

so you are getting mail per jobs in copy job, because you have 2 backup jobs inside of copy job, then you are receiving mail per job

But the same job is repeating  twice , please see the screenshot in my question .

Example : Physical Servers 10PM Daily Copy to Archive at 11:05 and 11:07 

i will be good if you will provide logs from job, to see, what is happening

Which logs - job or task?

Hi ​@Nikks -

You can look at the Veeam logs in C:\ProgramData\Veeam\Backup to verify where the emails are specifically coming from (hopefully). 

Maybe the others can navigate you to pinpoint where your notifications are coming from, but you can always open a case with Veeam Support to help you find the issue.

I am seeing this pattern

[23.03.2026 .757]    <23> [0006]    Info (3)    [SessionReportMailer] Sending report

[23.03.2026 .764]    <23> [0006]    Info (3)    [CReportMailer] Sending report to  ;  ;

Ok, so not really showing the source to help pinpoint the issue?

It’s really best if you open a Support case with Veeam to help you get sorted (if the others have no other ideas themselves).

100 000 timeout is 1.67 minutes

So looks that veeam it does not have respnse, so it will send in 1.67minutes again. That's why you see second mail in 2.minutes later ... Maybe your mail server has issue with SSL.

Thanks for the  answer. But it is only happening for this two jobs . Al  other are getting only single email and the settings are similiar - Copy mode 

one option could be that you have notification in enterprise manager enabled

and second that this copy job has tiering in destination storage that you have created restore point on primary copy and archive copy?

hard to answer if we do not know complete setup ...

Checked , no VBEM in our environment . Is it good to test it out having a new clone copy of this BCJ or create a new BCJ for this one to see duplicate issue exists?

Yes, thats good idea to clone copy job and with only one job inside...
