Backs up vaultwarden files and directories to tar.xz archives automatically. tar.xz archives can be opened using data compression programs like 7-Zip and WinRAR.

Files and directories that are backed up:

• db.sqlite3
• config.json
• rsa_key.der
• rsa_key.pem
• rsa_key.pub.der
• /attachments
• /sends

Usage

Automatic Backups

Refer to the docker-compose section below. By default, backing up is automatic.

Manual Backups

docker-compose
