We have set up an ArcGIS Portal with high availabillity.
When we now have tested failover, we see that it is generated alot of db<nnnnnnnn> folders. This seems to be created each time it tries to switch between primary and secondary Portal server. When is it safe to delete these folders? After a day or month?
They store a snapshot of the data at the time the portal returned to the configuration as the standby portal. Ideally there'd be a configurable retention policy, which is something we can hopefully get to in the future. Since they likely out of date data, you can delete them whenever you see fit.
