You can use the following link to search your Google Drive for the folder Vaulty created to backup your files:

Your backed up files are located within this folder and end in ".vdata"

As long as the following sync conditions are met, all files are automatically backed up:

1) Subscribe to Vaulty's automatic backup service

2) Have the newest version of Vaulty on your device

3) Authorize Vaulty to use one of your Google accounts for automatic backup

4) Make sure you are using the same Google account on your device that you used to purchase the subscription

***Automatic backup will only occur when you are connected to WiFi and are either charging your device or have at least 50% battery power on your device. You also have the option to set automatic backup on mobile data without WiFi.

Note: Automatic backup does not apply to files that you have manually deleted within Vaulty. Files that you have manually deleted cannot be restored.
