I have asked this question twice to techsupport but unfortunately I do not get an answer from them.
Maybe one of the community members knows the answers.

In the DCM driver there is a possibility to make backup to a specified location.
I configured this and it seems to work.

But now some DCMs make backups multiple times a day and others hardly ever. Why is this, what is the trigger that a backup is made?

And can it be set up so that a backup is made once a day at a fixed time?

Thanks in advance for the effort
