The migration of large communities from Reddit to Lemmy is like a world-renowned band performing an acoustic set in a library for 50 people. - eviltoast

The fanbase is still large, but the Lemmy community hasn’t quite caught up yet, and now there is a transitional period where the audience is smaller.

      Even just a cronjob or scheduled task to download the backups to a machine at another location would be a big improvement. Then you can do it far more often because it’s automated.

      But personally I like to have both a copy on a PC and a cloud backup, in addition to the server.

        I’m using the easy Lemmy script to run the docker instance. How do I take a backup of a running docker instance.

        The backups I’ve done so far are full shard backups. But I don’t have a way to automate that.

          The page here explains getting a database dump on a running instance (and how to restore): https://join-lemmy.org/docs/administration/backup_and_restore.html

          Then just back up the other files in the volumes directory where Lemmy is installed (everything except postgres, which is what the database dump does).

          The pictrs volume includes both the uploaded images and the image cache. I have no idea how to separate out the uploaded images so you don’t have to back up the cache, I just back it all up.

          this is the bash script I use to create backups

          #! /bin/bash
          # https://join-lemmy.org/docs/administration/backup_and_restore.html#a-sample-backup-script
          now=$(date +"%Y-%m-%d_%H.%M.%S")
          
          cd ~/lemmy && (docker-compose exec -T postgres pg_dumpall -c -U lemmy 1> dump.sql 2> dump.errors)
          cd ~/lemmy && zip -r9 ~/bak-lemmy-$now.zip ./ --exclude "volumes/postgres/*"
          rm -f ~/lemmy/dump.sql
          

          it creates very small zip files as a result so it’s very efficient

          I made a cron for it to run every 3 hours, like

          0 */3 * * * ~/lemmy/backup.sh
