Hello Support Team, I'm little bit confused between data location , vault, and backup. I'm using Enpass with 4 different vaults located in 4 different drive, 2 One drive and 2 Google drive and I mainly use Enpass in two devices (Computer and smartphone). Now when I'm looking at the settings in Desktop App or Android App, data location are set in local, however it seems taht I have exactly same data between my two devices. Then I'm not sure how Enpass works and mainly where my data are ? On drive or on local ? I would say on Drive because of the sync but what the local data is referring to ? In addition, what would be the best way to ensure regular backups ? On local or on Drive ? There is no troubleshooting on this topic but just some recommendation to understand the functionning and the best practice of this solution. Thanks for you help. Cervoise.
