With a little bit of editing - a note to all who will back up their data:
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-Browser folder (at least on desktop), which will contain their vBAT at the time of manual backup.
Linux OS:
$HOME/.config/BraveSoftware/Brave-Browser/
Mac OS:
/Users/username/Library/Application Support/BraveSoftware/Brave-Browser/
Windows OS:
C:\Users\username\AppData\Local\BraveSoftware\Brave-Browser\
