[Snapshot Pro] Help restore backup

We’re trying to restore a Snapshot Managed Backup with the Snapshot installer. But it is failing. The error message is quite inconsistent. At once, it completed but gave us a database error. The next time, it displayed a PHP warning saying that the server didn’t have enough space. Now that we’ve cleared server space, the installer no longer shows us the “Deploy” button. Could you help us restore the backup?
