Drop all database after restore

Hello everyone, I did some tests with urbackup and I’m having a serious problem.
Below the step-by-step performed in the tests

  1. Made the installation and configuration of the server and client
  2. Sql Server backup were started (Windows 2008 and SQL Server 2008 R2)
  3. All backup’s have been done successfully
  4. In the web panel a restore of the SampleData database was requested
  5. A message that Windows should restart has been requested and confirmed
  6. After restarting the server all databases have been deleted, only SampleData has not been deleted

Is anyone in the same trouble?

Note.: Do not test in production
