This is just a fork from jmqm/vaultwarden_backup with some personal changes

---

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

Pass manual to docker run or docker-compose as a command.

How to restore

1. Stop the application
2. Go to the data directory of your application ex. cd /vaultwarden/data (if that is my data folder)
3. Delete the db.sqlite3-wal rm db.sqlite3-wal (you dont need it since the backup was created using .backup)
4. Just extract tar -xJvf <backup-file.tar.xz> -C /vaultwarden/data
5. Run the application
