Firefly backup and restore scripts

firefly-backup

This script automatically creates a tar.gz archive of the firefly database and copies it to a secure offsite location.

It does NOT save the encryption key. Store that somewhere else securely (e.g. password manager).

I have firefly-backup running via a daily cronjob.

firefly-restore

This restores a .tar.gz backup of the firefly database to a docker volume. The script takes the filename of the backup as an argument and assumes a static location where those files are found.

Usage

  1. Modify the files with your preferred settings (BACKUP_TARGET, BACKUP_SOURCE etc).

  2. Make both files executable and place them in a user executable bin directory, something like /usr/local/bin. chmod +x firefly-restore firefly-backup mv firefly-restore firefly-backup /usr/local/bin

  3. Set a cron job to automatically run the script ln -s /usr/local/bin/firefly-backup /etc/cron.daily/firefly-backup
