Instant notifications of successful and failed backups

Four months ago, in February 2022, we received a new feature request from our user in our issue tracker. In the request, the user asked us to implement real-time notification support via messengers. As soon as a backup fails or succeeds, he should receive a notification. We found the request extremely useful and prioritized it in the backlog of our project. Despite the delay in delivery, we are happy to say that the work is done and the feature is now available.
