This is a Windows batch file that will backup multiple vaults and their attachments plus optionally, your family/organization vault.
Be forewarned: The batch file uses a config file where you save your credentials. YOU must put that file on encrypted media such as a VeraCrypt volume before putting your credentials in the file. Do not even temporarily save it outside your encrypted volume (or use a text editor that does that)! If you’re not sure how to manage that, I suggest you ignore this post.
Review the batch file and you’ll see that all it does is use the offical Bitwarden CLI and json parser (to process attachments). Nothing mysterious that might leak your info into unknown executables/other.
