+Please be informed that a backup does not store your configuration
+files.  One reason for this is that your database contains encrypted
+information for two-factor authentication.  Storing encrypted
+information along with its key in the same place defeats the purpose

+
 If you use an Omnibus package please see the [instructions in the readme to backup your configuration](https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md#backup-and-restore-omnibus-gitlab-configuration).
 If you have a cookbook installation there should be a copy of your configuration in Chef.

 ## Restore a previously created backup
 
 You can only restore a backup to exactly the same version of GitLab that you created it on, for example 7.2.1.
 
+### Prerequisites
+
+You need to have a working GitLab installation before you can perform
+a restore. This is mainly because the system user performing the
+restore actions ('git') is usually not allowed to create or delete
+the SQL database it needs to import data into ('gitlabhq_production').
+All existing data will be either erased (SQL) or moved to a separate
+directory (repositories, uploads).
+
+If some or all of your GitLab users are using two-factor authentication
+(2FA) then you must also make sure to restore
+`/etc/gitlab/gitlab-secrets.json` (Omnibus) or `/home/git/gitlab/.secret`
+(installations from source). Note that you need to run `gitlab-ctl
+reconfigure` after changing `gitlab-secrets.json`.
