Though Vaultedge is hosted on cloud, it can support offline data sitting in laptops or usb drives. When connecting a offline device to Vaultedge, Vaultedge will ask user to install a client program. This client program will help in categorization and creation of search index of the offline data. Once categorized and indexed, periodically the client program will redo the operations when there are changes to the data. When user clicks on such a offline file, Vaultedge has the ability to pull the file from the offline storage if the device is connected. Users also have the option of keeping a copy of such offline data within Vaultedge cloud for faster access. Thanks for the question. Please let me know if you have further questions.
