Show Backend statistics in report


How I can show Backend statistics in report because I would like the size of backup in cloud storage. The name of this information is KnownFileSize.

Thank you,

send-mail-result-output-format=Json seems to send. HTTP and XMPP have this option too (not tested).
JSON is less human-friendly though. Possibly third-party tools could help. dupReport says the following:

Supports both text and JSON status emails from Duplicati

Duplicati Monitoring gets HTTP feed. Topic talks size, but I’m not sure of status or source versus remote.
You can certainly check with the authors if you prefer a user-friendly report that also has the remote size.
