Problems with backup restore

When I try to restore a backup with the following commando: bundle exec rake gitlab:backup:restore RAILS_ENV=production BACKUP=1516275112 --trace it failed to restore all the Database tables. When I run this commando it says everything is [DONE].
But all database tables are empty.

Possible fixes

I changed the file lib/tasks/gitlab/db.rake line 29:

  •  tables.each { |t| connection.execute("DROP TABLE #{t}") }
  •    tables.each { |t| connection.execute("DROP TABLE IF EXISTS #{connection.quote_table_name(t)} CASCADE") }

Otherwise I got an error, a table could not be found.
I hope someone can help me.
