You might want to update your illustration . . . so that the Brave-Browser folder (parent for the ‘User Data’ folder) is backed up.
Re what @Saoiray reported from a recent Brave call:
In the meantime, users facing a situation in which they have no custodial option and need to back up their current vBAT can manually copy-paste/back up their
/brave-browserfolder (at least on desktop), which will contain their vBAT at the time of manual backup.
