:bookmark: This guide provides step-by-step instructions for creating, downloading, and restoring a backup of your Discourse database.

:person_raising_hand: Required user level: Administrator

Discourse allows site administrators to create and download a copy of the site’s database. The backup can then be uploaded and restored to any Discourse forum.

Discourse backups include the full site database, which contains everything on the site: topics, posts, users, groups, settings, themes, etc. Depending on how the backup file is created, it may or may not include uploads. See the next section for details.

Though the data created by plugins exist in the database, the plugins themselves are installed in your app.yml file. To restore your site to a new server you will need to make sure that your installation includes the plugins you require.

Create a backup

To create a backup of your Discourse site, follow these steps:

  1. Go to the Admin / Backups section of your site.
  2. Click the Backup button.

  1. A modal window will open asking you whether or not you would like to include the site’s uploads in the backup. Specify whether you want to include site uploads in your backup.

:warning: If your site is hosted by us and you would like to create a backup that includes uploads, contact the Discourse team before creating the backup.

Restore a backup

Before you are able to restore your backup file you need to enable the allow restore site setting. Then click the Restore button on the Backups page for the backup you want to restore.

:warning: Restoring a backup file will overwrite all data on the site. When the backup is restored, you will be logged out of the site and need to log back in with your credentials from the restored site.

:warning: Make sure the site you are restoring into is running the same version of Discourse as the old site. It is best to update both sites to the latest version before running the backup/restore process.

The restore process automatically sets the disable emails setting to “non-staff”, so emails aren’t sent to your site’s users until you’re ready.

:discourse: If your site is hosted by Discourse, the Restore button in the screenshot below will be disabled. After uploading the backup file, contact the Discourse team and let us know the name of the backup file that you wish to restore. We will restore it for you.

Command line backup and restore

For administrators comfortable with the command line, you can create and manage backups programmatically:

  • Backups are stored in /var/discourse/shared/standalone/backups.
  • Start a backup using:
./launcher run app discourse backup

or

docker exec app bash -c "discourse backup"

For more information about command line backups, see: Backup discourse from the command line.
