Backup your essential Mastodon files to an S3 bucket!

This set of scripts was created to automate some of the basic maintenance that I would normally use to cleanup and make backups of my mastodon instance.

Feel free to use this backup script to help keep your instance clean too!

Configure the AWS credentials

  • Install the AWS CLI

    • NOTE: This script requires that aws configure has already been completed for the root user before being ran for the first time

  • Fill out the example_config.sh file with your information for AWS, and then move it to config/config.sh

Prepare the script files

  • Set the two files as executable:
chmod +x backup.sh
chmod +x config/config.sh

Cronjobs

Setting up automated backups

  • Add this line to your root crontab to ensure that the backups are being ran daily and a log is being generated:
0 3 * * * /opt/mastodon-backup/backup.sh > /opt/mastodon-backup/logs/backup.log 2>&1

Weekly restart of server

  • Add this line to the root crontab to ensure that a weekly restart is occuring:
0 0 * * 0 /sbin/shutdown -r now

Automatic media cleanup

  • NOTE: This should be set for the mastodon account and not set as the root user

  • Add this line to the mastodon user's crontab to ensure that the media is being cleaned out daily and capped at 7 days:
@daily cd /home/mastodon/live && RAILS_ENV=production bin/tootctl media remove --days=7

Restart Cron

  • After making changes to crontab, restart the cron service:
sudo service cron restart
