1. Stop the Pleroma service.
2. Go to the working directory of Pleroma (default is `/opt/pleroma`)
3. Run `sudo -Hu postgres pg_dump -d <pleroma_db> --format=custom -f </path/to/backup_location/pleroma.pgdump>` (make sure the postgres user has write access to the destination file)
4. Copy `pleroma.pgdump`, `config/prod.secret.exs` and the `uploads` folder to your backup destination. If you have other modifications, copy those changes too.

2. Stop the Pleroma service.
3. Go to the working directory of Pleroma (default is `/opt/pleroma`)
4. Copy the above mentioned files back to their original position.
5. Drop the existing database and recreate an empty one `sudo -Hu postgres psql -c 'DROP DATABASE <pleroma_db>;';` `sudo -Hu postgres psql -c 'CREATE DATABASE <pleroma_db>;';`
6. Run `sudo -Hu postgres pg_restore -d <pleroma_db> -v -1 </path/to/backup_location/pleroma.pgdump>`
7. If you installed a newer Pleroma version, you should run `mix ecto.migrate`[^1]. This task performs database migrations, if there were any.
8. Restart the Pleroma service.
9. Run `sudo -Hu postgres vacuumdb --all --analyze-in-stages`. This will quickly generate the statistics so that postgres can properly plan queries.
5. Drop the existing database. `sudo -Hu postgres psql -c 'DROP DATABASE <pleroma_db>;`
6. Restore the database schema and pleroma postgres role the with the original `setup_db.psql` if you have it: `sudo -Hu postgres psql -f config/setup_db.psql`.
Alernatively, run the `mix pleroma.instance gen` task again. You can ignore most of the questions, but make the password the same as found in your backup of `config/prod.secret.exs`. Then run the restoration of the pleroma role and schema with of the generated `config/setup_db.psql` as instructed above. You may delete the `config/generated_config.exs` file as it is not needed.
7. Now restore the Pleroma instance's data into the empty database schema: `sudo -Hu postgres pg_restore -d <pleroma_db> -v -1 </path/to/backup_location/pleroma.pgdump>`
8. If you installed a newer Pleroma version, you should run `mix ecto.migrate`[^1]. This task performs database migrations, if there were any.
