I found that the gwbk file was getting larger over time for a project. I changed the .gwbk file to a .zip file and opened to find most of the disk space (147 of 170 MB) was in a history file: \modules\com.inductiveautomation.taghistorian\HistoricalData.idb

Is it possible to exclude the internal historian data from the backup?
