Duplicati

Duplicati has email reporting built in, set with advanced options on each backup. Its default subject names the backup, so one client address covers several backups.

1. Open the backup's options

   In the Duplicati web interface, choose the backup → Edit → Options (step 5) → Advanced options.

2. Add the email options

   Add these advanced options:

   • send-mail-to: the client address
   • send-mail-url: your SMTP server, for example smtp://smtp.example.com:587/?starttls=when-available
   • send-mail-username and send-mail-password, if your server needs them
   • send-mail-from: the sender address your server accepts
   • send-mail-level: All, so successful runs are reported too

3. Keep the default subject

   Leave send-mail-subject unset. The default, "Duplicati Backup report for <backup name>", is what the built-in rule reads the name from.

4. Name the backups the same

   In BackupSentinel, give each backup exactly the name of its Duplicati backup. To apply the same email options to every backup at once, set them under Settings → Default options.

How reports find their backup

The built-in rule reads the backup name from "Backup report for <name>" in the subject, and the duration. One client address therefore covers all of a client's Duplicati backups, as long as the names are the same on both sides.

Check it works

Run the job once, or wait for the next scheduled run. Within a minute the report appears under the backup, or in the Inbox when it could not be matched. A product's own "send test email" is not a backup result: expect it in the Inbox, where you can ignore it.
