Mastodon: Manual backups

This is an updated version (26-08-2024)

This manual is a transcript of the way that I have made a backup of my Mastodon instance. Please make sure you are careful and use your brain while following this manual.

Preparing the backup folder

  1. Log in as root
  2. cd /home/mastodon
  3. mkdir backups
  4. cd backups

Making the backups

  1. Database (three steps)
  2. #NOTE: You might need to elevate to ROOT first before entering the commands in this section below.
su - mastodon
cd /home/mastodon/backups
pg_dump -U mastodon mastodon_production -F t > DATE_FILENAME.tar

    Example: pg_dump -U mastodon mastodon_production -F t > 2024-02-02-mastodon_production.tar

  3. Settings file (one step) 
    cp /home/mastodon/live/.env.production /home/mastodon/backups/DATE_.env.production

    Example: cp /home/mastodon/live/.env.production /home/mastodon/backups/2024-02-02-.env.production

  4. Redis (two steps, perform as root) 
    exit
cp /var/lib/redis/dump.rdb /home/mastodon/backups/DATE_dump.rdb

    Example: cp /var/lib/redis/dump.rdb /home/mastodon/backups/2024-02-02-REDIS-dump.rdb

You can now check your backups folder to see if all three files are present. This is also a good moment to copy the backup files to another, safe, location.

If you wish to backup your assets like images and stuff (User-uploaded files), backup the folder named “public/system”. Keep in mind that this folder can be rather large. Actually, it can become rather massive.
