Problem
There is no easy solution for external monitoring of the backups. Since there's nothing worse than setting up a backup to discover after 6 months (or years) that it stopped working after a couple of days.
Yunohost sending mails alleviates the problem somewhat, but it doesn't protect against silent failures.
This PR fixes #117 - it can be extended later on by multiple options for backup monitoring, something like the backup-hooks in borgmatic, but it doesn't have to.
Solution
Introduce an optional config-variable called
healthchecks_url
that is called upon success or failure (in the event of failure it includes the logs). You can send this either to your own hosted version of healthchecks.io or to the official one.PR Status
