When performing a WebGISDR restore (full or incremental), ArcGIS Data Store backs up files into the directory "C:\arcgisdatastore\backupedContents<date>". We wish there was a way to prevent this backup prior to the restore, accepting the risks that if the restore fails there would be no rollback to anything or even just a rollback to a clean slate (no data).
Use case:
In our environment when performing a WebGISDR restore it takes well over an hour to backup our 500GB pgdata folder to the directory mentioned before the software even starts the restore. Having 99.9% availability requirements, every hour truly counts when doing a restore.
We love that when performing an upgrade of Portal there’s an option to not back up the content directory, accepting the risks of a failed upgrade. This saves us several hours. We just wish there was something similar for WebGISDR restores of Data Store.
