I have enabled the scheduled backup to run at 23:00 daily.However even though there is no change, it still takes a backup of all devices. Is there a way we can avoid this? It would be really useful.
It is necessary to get configurations from every device to make possible compare them. ConfiBack downloads configuration, takes the most recent from its database and compares them. If it founds them different, it saves a new version. If they are the same, configuration isn't saved, but discarded. What makes you confused is probably the message "Saving into database". It's semantic bug, because the comparision follows right after the message. So there would be different message.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
