Backup Script

Bash script that can be run on a cronjob to backup a Minecraft server.

Requirements

• Linux
• Server running via Pterodactyl Panel
• Discord webhook (for notifications)
• Duplicacy installed

Usage

Initial Setup

Generate an asymmetric key pair for encryption

openssl genrsa -aes256 -out private.pem 2048
openssl rsa -in private.pem  -pubout -out public.pem

Copy .env.example as .env and fill in the required secrets

cp .env.example .env

Initialize the repository

./backup.sh -i /my/folder/to/backup

Backup filter

To update the file include/exclude filter, modify the filters file before performing your backup.

See https://github.com/gilbertchen/duplicacy/wiki/Include-Exclude-Patterns for details.

To test what will get included/excluded, perform a backup as a dry-run.

# Print everything included/excluded
./backup.sh -d

# Print only what will be excluded
./backup.sh -d | grep 'PATTERN_EXCLUDE'

# Print only what will be included
./backup.sh -d | grep 'PATTERN_INCLUDE'

Backup

./backup.sh

To automate this with a cronjob:

0 0 * * * cd /your/path/pcb-minecraft-backup && /bin/bash ./backup.sh

Important

The cd is required because the script assumes it is being run from the git repo directory
