Comment subscriptions are no longer possible because the subscription function of the Joomla comment plugin I use doesn't comply with GDPR.
I tried to find a Joomla comment plugin which supports double opt in but failed. If you know a Joomla comment plugin which supports double opt in please let me know 
Therefore you have to check for comment updates manuallĂ˝ now
.
If you have questions or problem reports for raspiBackup just create a github issue. That's my preference because that way I can track any questions and problem reports quite easy. You also can create a comment on Facebook. Both services will send you a comment update notification.
Sorry for the inconvenience. But that's a consequence of GDPR.
