Would it be great to have a checkbox on the entitys if you want to turn on historian data on 1 item that you want to keep
If you want it now, it keeps everything about the device and it is just junk.
I read about it that a lot of people are getting very large backups because of it. (20Gb and more, increasing day by day)
If we had such an option, it would save large diskspace and backuptime. So it would be green too !! Good for the environment !! It would even be better to get the history on another disk or network so it does not interfere with the system at all.

I love you work
