Duplicati 2.0 has options for email alerts, which is really great. No backup system should be without email alerts, or alerting of some kind.
To set it up, you need to access the Settings page and scroll down.
We’ll be using TLS to connect to Office 365.
While you can add the options via GUI, I find it easy to add as text once you know the syntax. Below is what I’m using and it works great.
–send-mail-subject=Duplicati %OPERATIONNAME% report for %backup-name%
I have mine set to send emails for “any operation” instead of just on error, but if you want to change this, add the above options via the text, and then edit the options in the GUI.
