Updated a two node XCP-ng 8.0 homelab without any issues

You need to enable and configure the backup-reports and transport-email plugin under setting - plugins. backup-reports just needs the recipient mail address. transport-email needs the mail service connection settings in the transport section (you get this settings from your mail provider) and a valid sender mail address.

When you configure a backup job, you can then choose when you want to receive a notification (settings block bottom left). Settings are self explanatory (Always vs. Failure). That's it and I hope it helped.

@borzel: I second that! From time to time, I try to move over to XOA, but I always keep coming back to XCP-ng Center. XCP-ng Center supports my administrative tasks in a straight forward way (at least apart from backups ) and gives me all the information I need. Thank's for doing a great job!

I wonder if the backup (and restore) traffic is going through XO (on the management network) or does XO advise the xcp-ng host where the backup remote store (on the storage network) is, so that the traffic stays on the storage network? Read some articles on the XO forum and the internet, but did not get a clear picture on the recommended architecture.
